• Overclocking a Windows 10 hard drive. Optimizing the performance of the hard drive

    Probably all users want their computers to be able to perform the required actions much faster than they currently can. Information processing can be accelerated in different ways. Such options include optimizing the operation of the hard drive. For such a process, Windows has a huge number of settings and tools. Let's look at how to speed up work hard disk and the overall operation of the computer.

    Disabling indexing

    This method is suitable for those who do not use the search function in the operating system.

    The basis of the method is to close the hard drive partition from indexing, which will speed up its operation. To do this:

    1. Go to “My Computer”. There you need to call up the context menu on the main drive, often the C:\ drive. Then click “Properties”.
    2. In the “General” menu, select “Allow content to be indexed...”. You need to uncheck the box and confirm the action.
    3. After these actions, a notification will appear informing you about the possibility of using the new policy only for certain files. Select “Continue” and then “Skip all”.

    Stop logging

    IN standard settings The system has a logging function. All failures and changes made are displayed there. If this system If you don't use it or don't even understand what it means, you can safely disable it.

    Disabling instructions:

    1. Launch command line. Most the simplest way: Press “Win ​​+ R”, and in the “Run” window that appears, enter “cmd”.
    2. An application will open where you need to enter: fsutil usn deletejournal /D C:, where C is the letter of the required hard drive.
    3. To confirm your intentions, you need to press “Enter”. Then the command prompt must be closed.
    4. For the changes to take effect, the computer must be restarted.

    Cleaning up unnecessary files

    Quite often speed indicators work hard disks improve noticeably after removal Not necessary files who are for long time could be collected on storage. The more free space on the hard drive, the faster the search for files will occur, and this will speed up the work.

    If we consider this process in more detail, it turns out that the system will not carry out a long search in its tables for the address of certain pieces of information. By deleting unnecessary data, the number of such tables will be less than if the space is full.

    Therefore, you need to delete files from your computer that are not in use more often. If they are important, then you can simply collect them in one folder and archive them. Such a procedure will free up space, and there will be only one address in the parameters of the main table.

    To clean disks in Windows 7 and other versions, special tools are used. They are located in the Start menu under the Utilities category. The exact name is “Disk Cleanup”. The program searches for unused files in the partition and then prompts the user to delete them.

    In addition there is large number programs that support this procedure.

    Defragmentation

    When new information is written to the device, it is not always located nearby. Individual packages are placed on the free space of the volume. After numerous recordings, one file can be located throughout the media. This results in the system constantly accessing different sectors. Using defragmentation, you can search for similar data and collect it together. The system will then contact neighboring locations, which will increase the speed of operation.

    Such a tool can only help when using HDD drives.

    The function is available in various programs that offer services to speed up your computer.

    Microsoft operating systems have the ability to defragment using built-in capabilities. To do this, in “Computer” you need to select required disk and launch the context menu. Then select “Properties”, select “Service” and select “Optimize”. The OS will then prompt you to defragment.

    Re-partitioning

    In cases where the computer is used for a long time and the hard drive is running on full power, you can re-label. This will help if you have two or more partitions.

    This is formatting the disk, and some developers indicate that it is being “cut” again hard drive into sectors and tracks.

    The ideal option is when the system uses one hard drive with a single volume. A system with two partitions is considered normal. At more– the system will work more slowly, spending time searching necessary files. IN this process search is carried out on all hard drives one by one. You can use one hard drive to install the OS and software, and record movies and other multimedia files on the other.

    Moving files to removable media

    A good option is to move unused data to separate media. Often used for this external drives. It is important to choose reliable external HDDs that will differ high speed information processing.

    The products can be used not only to store outdated files, but also in the form of a flash drive. For such purposes, 500 GB will be enough. It connects to a computer via a USB interface and is characterized by silent operation.

    Disabling startup programs

    Availability unnecessary programs in startup significantly slows down the computer and uses its processor and memory. If you disable them, you can increase disk speed and overall system performance.

    In different Windows versions startup control is located in different places. It is most convenient to use the CCleaner utility for this purpose. You need to launch the utility and go to the “Tools/Startup” menu.

    In startup you should leave only those programs that are necessary for the computer to operate, for example, antivirus. The remaining components can be disabled using the “Disable” button in the right panel.

    Any of the disabled programs can always be started again manually. If the icon will disappear in the system tray, then it can be launched again using the “Enable” button.

    Updating the Disk Controller Driver

    The stability of the entire system depends on the relevance of the drivers. It is recommended to update drivers to latest version, this is especially true for SSD drives.

    To check the version installed drivers you need to go to “Device Manager”. You need to open the command line, and enter “devmgmt.msc” in it and press “Enter”. Then right-click on SATA controller and select “Properties”.

    If used old driver, then a new one can be found on the manufacturer’s official website motherboard or laptop, download and update it.

    There are special utilities, which allow you to update drivers. You can select software " Driver Booster", which, when launched, will show a list of drivers that require an update.

    This information will help you optimize your hard drive and improve its performance.

    How to speed up your hard drive and your computer in general - the best methods and my personal experience

    Greetings, dear readers, Trishkin Denis is here.

    Many users want their computers to perform tasks faster than on at the moment. You can speed up the information processing process in different ways, one of which is optimizing the operation of your hard drive. For this purpose, Windows provides a lot of tools and settings. By doing everything described below, you can speed up your hard drive and your computer as a whole.

    Methods for optimizing work (to contents)

    The Microsoft operating system provides many tools that allow you to speed up the device by a minimal amount.

    Here are the main ones:

      Disable indexing.

      Opting out of journaling.

      Cleaning up unnecessary files.

      Defragmentation.

      Re-partitioning.

    Disabling indexing (to content)

    This method is only suitable for those who do not use operating system search.

    The point is that the method involves closing hard section disk from indexing, which allows you to speed up its operation. To do this:


    Opting out of journaling (to contents)

    By default, the system has a logging function installed, which displays all changes and failures. If you don’t use this system or don’t even know what it is, you can safely disable it.

    To do this you need:


    Cleaning unnecessary files (to contents)

    You can often increase the speed of your hard drive by using easy removal extra documents for for a long time usually a lot of people gather. You need to understand that the more free space on a hard drive, the faster it finds files, which means its speed is higher.

    If we consider this process in more depth, it turns out that the system does not need to spend a long time searching in its own tables for the address of a piece of information, because in this case it has less similar data than if the partition is completely filled.

    That is why it is necessary to delete unused files from your computer more often. If they are important, collect everything together and archive it. This will free up space, and most importantly, now there will be only one address in the main table.

    There is a special tool for cleaning disks in Windows 7 and other versions. It is in start-up utilities. This is called “Disk Cleanup”. It looks for unused files in the section and offers to delete them. In this article I described how to delete old windows updates 7 using this tool. You can read it, it will be useful!

    increase

    In addition, there are a lot of programs that allow us to do the procedure we need. You just have to do a little searching on the Internet.

    Defragmentation (to contents)

    When new information is written to a device, it may not always be nearby. Individual packages are placed on the free space of the volume. It turns out that after numerous recordings, one file can be scattered throughout the media. Because of this, the system needs to constantly access different sectors. Defragmentation looks for such data and brings it together. In the future, the system will already access neighboring places, and therefore the speed of operation will increase.

    Important! This tool will only help if you are using HDD standard disks.

    The function is present in many programs that offer computer speedup services.


    At the same time, in Microsoft OS, defragmentation can be carried out using built-in capabilities. To do this, you need to select one of the drives in “Computer” and call up the context menu. Next, click “Properties”. Then go to “Service” and click “Optimize”. After this, the OS itself will offer to carry out the above operation.

    Re-labeling (to contents)

    In the case when you use your computer for a long time and at the same time use the capabilities of the hard drive to its full capacity, sometimes it is worth re-partitioning. This will help if you have two or more partitions.

    Thus, you format the disk, and some developers claim that they “cut” the hard disk again into sectors and tracks. But earlier I wrote that these are just “loud words”, because this kind of thing only happens at the manufacturing plant.

    It should be noted that it is ideal when one hard drive in the system has a single volume. Two sections are considered normal. If it is more, the system will work longer since the search for the necessary files will be carried out one by one for each one. So, for example, you can allocate one hard drive on which the operating system and programs will be installed, and another for storing films, photos, music and other information.

    More details about the methods division of hard disk you can read in this article

    Moving files to removable media (to contents)

    Another good option is moving unused documents to a separate medium. External drives are often used for this. Many call 2.5 "one of the best today external HDD WD Elements Portable. It is distinguished by its quality of execution and speed of data processing.

    It can be used for more than just storage old information, but also use it as a flash drive. And we can safely say that 500 GB will definitely be enough for these purposes. It connects to the computer via USB. It works silently.

    The device is lightweight - only 134 g, as well as a matte surface, which allows you to avoid unwanted fingerprints.

    Buy to order this external hard disk you can here.


    Personal experience (to contents)

    On Windows that came out before the seventh version, defragmentation usually made things even worse - the computer worked slower after it. But in the last few operating systems from Microsoft, the algorithm for this tool has clearly changed. Therefore, after carrying out the next process of reuniting files, the difference in a positive direction is clearly visible.


    For convenience, I use a program from Auslogics. It contains all the tools that allow you to clean your computer in the shortest possible time and speed up its operation.

    How to improve hard drive performance - Free-IT-expert

    To improve the performance of your hard drive, you need to switch it to AHCI mode. Advanced Host Controller Interface (AHCI) technology is a standard proposed by by Intel, allowing you to increase the speed of reading/writing operations with hard drives connected via the SATA protocol, through the use of advanced features of SATA technology, such as integrated command queuing (NCQ), in addition, the standard supports hot swap technology for hard drives.

    The fact is that in the BIOS of your motherboard it is possible to select the operating modes of your hard drive. Exhibited this parameter in Configure SATA and has 3 operating modes - Standard IDE/AHCI/RAID.

    The default is StandardIDE, which means that your hard drive SATA drive will emulate IDE work, an older and correspondingly slower interface. Let's change this misunderstanding to AHCI.

    Remember: this function, only works when presence of hard disk with SATA interface.

    In addition, if you set the AHCI mode when installed windows, then in response when loading windows, you will receive blue screen death. You can get rid of it in the following way:

    1. Open the Registry Editor by typing RegEdit in the Start bar. 2. To the UAC request “Do you want to allow the following program to make changes to this computer?”, answer Yes. 3. In the registry editor, go to the following branch: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\msahci 4. In the right pane, select the Start key and edit it (Modify).

    Increasing the speed of the hard drive. Methods that will add up to 20% speed!

    The speed of the operating system, gaming performance, data processing speed of various programs, all these parameters directly depend on the speed of the hard drive. If you are negligent in periodically checking and optimizing the operation of your hard drive, you risk reducing its performance, and in the worst case, losing the data stored on it.

    In order to increase the speed of the hard drive and ensure its correct and stable work, it is worth performing such operations as defragmentation and checking the disk, etc.

    Check your hard drive

    This check should be performed at least once a month. It allows you to check all parts of the hard drive for bad sectors and system errors. In order to run this check, go to properties local disk. On the “Service” tab, click the “Run check” button. In the window that opens, select the checkboxes that you need and then click the “Run” button.

    The utility will check the entire hard drive in several stages and correct all errors. It's worth remembering that this check can be performed on non-system drives. To check the system disk, after clicking the “Run” button, the utility will ask you to reboot and only then will it begin checking.

    In order to run this check from the command line, run the command: chkdsk C:, where “C:” is the drive that we want to check.

    Defragment your disk

    Defragmentation is a process that allows you to update and optimize the structure logical drive, in order to organize the placement of data in the correct sequence. The result of defragmentation is the rewriting of data into sequentially located (contiguous) sectors.

    You can start defragmentation on the “Service” tab, in the local disk properties.

    In the window that opens, select the disk on which you want to perform this procedure and click the "Defragmentation" button.

    The system will analyze and begin defragmenting the disk.

    Optimize your hard drive

    In order to optimize the performance of the disk, launch the Device Manager, to do this, select this item in the properties of “My Computer”. In the window that opens, select the tree " Disk devices" and in the properties of the desired disk, go to the "Policies" tab. Check the “Optimize for execution” and “Enable improved performance” checkboxes.

    Make more free space on your local drives

    Remember that cluttering the local disk directly affects its speed. Therefore, try not to fill it more than 70-75%. Pay special attention to system drive C! IN ideal it should have about 50% free space.

    Set up and optimize your page file

    Pay attention! Do not confuse the slow operation of the operating system with the operation of the hard drive! Often the cause of freezes and unstable work is precisely problems in the operation of the operating system (viruses, files remote programs in the registry, etc.).

    Over time, each computer user begins to work slower: files and folders take longer to open, the speed of reading and writing files becomes slow, etc., the computer is no longer the same as it was immediately after purchase.

    All problems that arise directly affect the productivity of our labor. Over time, all this just begins to infuriate. But you can work with this and try to restore that previous fast work, especially if the system, or rather its unoptimized operation, is to blame for these brakes.

    In this article we will look at, how to optimize hard drive and the entire computer in general.

    Update your hardware.

    Of course, there is no need to update and install new components every time something new appears on the market; this is very expensive. You can just install it sometimes new component, if necessary, especially for a video card for those who like to play modern games, RAM and processor.

    Perform a hard drive cleanup.

    Clear hard drives on your computer from unnecessary garbage can be done either manually or using special programs. If you do this manually, then look and delete files that are not used or not needed at all, but simply take up space. All this is done manually for quite a long time, but it is worth it.

    The second way is to find a special program on the Internet that will scan your computer and find all unnecessary and unused files. All you have to do is look at what the program recommends deleting, then check the boxes and click delete. Most often in programs everything is arranged something like this.

    It's best to use both methods to clean your disks at once. Delete files and folders that we don’t need ourselves, and let the program search for temporary files, temporary Internet files, empty the recycle bin, and so on.

    For cleaning system disk More often than not, using the standard Disk Cleanup function is always an effective way. Go to the Properties of the disk on which the operating system is installed and click on the Disk Cleanup more often button. Most often, this way you can remove about 1 gigabyte of various garbage. Sometimes more, it all depends on when the last time the cleaning took place.

    Defragment the disk.

    All the files that we store: movies, music, photos, can be divided into several parts and recorded on different parts hard drive. We see this, for example, how our just downloaded movie lies on the disk (D:) in one place, in fact it can be recorded on the surface of the hard drive in different places. It will take us much more time to open it if it were recorded in only one place on the disk. This is the case with many other files.

    By using hard defragmentation disk fragments are collected and written to one place.

    Defragment your hard drive You can use the program built into the system. For example, in Windows XP, to do this, you need to right-click on the disk, in the list that appears, select Properties, in the window that opens, go to the Tools tab, then click the button Run defragmentation loan Analysis and again Defragmentation.

    You can also find special programs on the Internet that work more thoroughly with defragmentation; as usual, you can find both free and paid ones. To do this, you need to use a search engine and a query like: “programs to defragment your hard drive.”

    Install a good antivirus program.

    Viruses can have a very detrimental effect on your computer. Virus creators and distributors can gain access to personal data on your computer and steal or damage it. To avoid this you need to have good antivirus program and constantly update its databases, since a bunch of new ones that are not yet known to antiviruses are released every day malware. Therefore, constant updating antivirus protection simply necessary.

    Regularly updating the databases will reduce the risk of infecting your computer to almost zero, although there is always a danger; no antivirus program can guarantee one hundred percent protection. But with most modern viruses antivirus programs cope.

    But to be fair, it is worth noting that antivirus programs not only protect us from viruses, but also provide additional load on PC and hard drive. The computer slows down slightly, but we can’t do anything about it, since today using an antivirus is simply necessary.

    Check your hard drive for bad sectors.

    The main reasons for the appearance of bad sectors on a disk are shaking, impacts, and the like. Damaged sectors will no longer take part in the work, so they need to be marked as unused. Modern disks have spare sectors and for auto remapping to them, the computer must first see them.

    The Windows operating system has this feature. Let's consider how to check your hard drive for bad sectors in Windows XP. To do this, we need to go to My Computer, right-click on the disk there, select Properties in the drop-down list, in the window that opens go to the Tools tab, then click on the button Run check, in the window that opens, check both boxes Automatically fix system errors and Check and repair bad sectors and then click the Run button.

    Using the above tips you can significantly optimize disk performance.

    A hard drive is a device with a low, but sufficient speed for everyday needs. However, due to certain factors, it can be much less, as a result of which the launch of programs, reading and writing files slows down, and overall work becomes uncomfortable. By taking a number of steps to increase the speed of the hard drive, you can achieve a noticeable increase in the performance of the operating system. Let's look at how to speed up your hard drive in Windows 10 or other versions of this operating system.

    The speed of a hard drive is affected by several factors, ranging from how full it is to BIOS settings. Some hard drives, in principle, have a low operating speed, which depends on the spindle speed (revolutions per minute). Old or cheap PCs usually have a HDD with a speed of 5600 rpm, and more modern and expensive ones - 7200 rpm.

    Objectively, these are very weak indicators compared to other components and capabilities of operating systems. HDD is a very old format, and it is slowly being replaced. Previously, we have already compared them and told how long SSDs last:

    When one or more parameters affect the performance of the hard drive, it begins to work even slower, which becomes noticeably noticeable to the user. To increase speed, you can use both the simplest methods related to file systematization, and changing the disk operating mode by choosing a different interface.

    Method 1: Cleaning your hard drive from unnecessary files and junk

    This seemingly simple action can speed up the disk. The reason why it is important to keep your HDD clean is very simple - overcrowding indirectly affects its speed.

    There may be a lot more junk on your computer than you think: old dots Windows recovery, temporary data from browsers, programs and the operating system itself, unnecessary installers, copies (duplicates of the same files), etc.

    Cleaning it yourself is time-consuming, so you can use various programs, caring for operating system. You can get acquainted with them in our other article:

    If you do not want to install additional software, you can use the built-in Windows tool called "Disk Cleanup". Of course, this is not as effective, but it can also be useful. In this case, you will need to clean out temporary browser files yourself, of which there are also a lot.

    You can also start additional storage, where you can move files that you don’t really need. Thus, the main disk will be more unloaded and will start working faster.

    Method 2: Smart Use of a File Defragmenter

    One of the favorite tips for speeding up the disk (and the entire computer) is defragmenting files. This is really relevant for HDDs, so it makes sense to use it.

    What is defragmentation? We have already given a detailed answer to this question in another article.

    It is very important not to abuse this process, because it will only have a negative effect. Once every 1-2 months (depending on user activity) is enough to maintain the optimal state of the files.

    Method 3: Cleaning startup

    This method does not directly affect the speed of the hard drive. If you think that your PC boots slowly when you turn it on, programs take a long time to start, and the culprit is slow work disk, then this is not entirely true. Due to the fact that the system is forced to launch the necessary and unnecessary programs, and the hard disk has a limited speed in processing Windows instructions, and the problem of slowdown occurs.

    You can understand startup using our other article, written using Windows 8 as an example.

    Method 4: Change device settings

    Slow operation of a disk may also depend on its operating parameters. To change them you need to use "Device Manager".

    Method 5: Correcting errors and bad sectors

    From hard state disk depends on its operating speed. If it has any file system errors, bad sectors, then processing of even simple tasks may be slower. There are two options to fix existing problems: use special software from various manufacturers or built into Windows check disks.

    We have already told you how to eliminate HDD errors in another article.

    Method 6: Changing the hard drive connection mode

    Not even very modern motherboards support two standards: IDE mode, which is mainly suitable for old system, and AHCI mode is newer and optimized for modern use.

    Attention! This method is for experienced users. Get ready for possible problems with OS loading and other unforeseen consequences. Despite the fact that the chance of their occurrence is extremely small and tends to zero, it is still present.

    While many users have the option of changing the IDE to AHCI, they often don’t even know about it and put up with the low speed of the hard drive. Meanwhile, this is quite effective way HDD acceleration.

    First you need to check what mode you have, and you can do this through "Device Manager".

    1. On Windows 7, click "Start" and start typing "Device Manager".

      On Windows 8/10, click on "Start" right click and select "Device Manager".

    2. Find a thread "IDE ATA/ATAPI Controllers" and unfold it.

    3. Look at the names of the connected drives. You can often find names: "Standard Serial ATA AHCI Controller" or "Standard PCI IDE Controller". But there are other names - it all depends on the user’s configuration. If the name contains the words “Serial ATA”, “SATA”, “AHCI”, then a connection via the SATA protocol is used; with IDE everything is the same. In the screenshot below you can see that an AHCI connection is being used - the keywords are highlighted in yellow.

    4. If you cannot determine the connection type, you can look in the BIOS/UEFI. This is easy to determine: what setting will be written in BIOS menu, which is currently installed (screenshots of the search for this setting are a little lower).

      When IDE mode is connected, switching it to AHCI must begin with the registry editor.


      If this method does not help you, check out other methods for enabling AHCI in Windows at the link below.

      We talked about common ways to solve the problem associated with low hard drive speed. They can give an increase HDD performance and make working with the operating system more responsive and enjoyable.

    Windows 7 uses the hard drive to retrieve document and application data and to temporarily store data in a page file. Therefore, optimizing your hard drive can significantly improve overall performance Windows systems 7. The next few sections provide some tips on how to do this.

    Examining hard drive performance metrics

    If you need to add another hard drive to the system, you should start by checking it, namely, by studying its theoretical performance indicators. The three most important things to pay attention to are the speed of the hard drive, the size of the cache it supports, and the time it takes to find the desired track.

    Hard drive speed

    Hard drive speed refers to how fast the drive spindle rotates, and is therefore measured in revolutions per minute (RPM). In general, the higher the RPM value, the better performance disk. Most hard drives have a spin speed of 7200 rpm, although older drives may have a spin speed as low as 5400 rpm. Older drives should be avoided as their performance figures appear to be significantly lower and the cost is not much different from 7200 RPM drives. In addition, 10,000 rpm drives are also available to significantly improve productivity.

    Hard drive cache

    The hard disk cache refers to the RAM area built into it. This memory is used to store frequently used pieces of data. When it finds needed data in the hard drive cache, the CPU saves time because it allows it to load the data directly into memory instead of asking the hard drive to retrieve it from the disk surface. How larger size hard drive cache, the more data it can store, and therefore the higher the likelihood that the CPU will be able to find the necessary data in the cache; as a result, the overall performance of the hard drive will be higher. Inexpensive hard drives typically come with a 2MB cache, while typical hard drives typically have 8MB or 16MB cache. Some high-end drives can have cache sizes of up to 32 MB.

    For any existing disk, the optimization process is the same maintenance process and therefore requires the implementation of an appropriate plan. For example, for a hard drive, such a plan might involve doing the following:

    • monitoring the amount of free disk space so that it does not become too small;
    • periodically removing any unnecessary files from the disk;
    • removing any unused programs and devices;
    • Frequently checking all sections for errors;
    • Regular defragmentation of partitions. Disabling compression and encryption

    Disabling compression and encryption

    If you use partitions on the disk with file system NTFS, Windows 7 allows file compression to save space, as well as file encryption for security purposes. (“Convert FAT16 and FAT32 partitions to NTFS.”) However, from a performance point of view, it is better not to use compression and encryption technologies unnecessarily, since both of these technologies slow down disk access due to the processes associated with compression/recovery and encryption/decryption procedures .

    Disable file content indexing

    In Windows 7 there is background process, which is called an indexer and indexes the contents of the disk on the fly as data is added or removed. This significantly speeds up the work of search tools in Windows 7 (including search tools instant search) because it lets Windows 7 know what the contents of each file look like. However, to improve overall performance, especially on drives where file searches are rarely performed, it is best to disable content indexing (this does not result in the loss of the ability to search by file properties). The steps required for this are listed below.

    1. Select Computer from the Start menu.
    2. Right click on the desired disk and then select in context menu Properties item. Windows 7 will display a property sheet for the drive.
    3. On the General tab, uncheck the Allow the contents of files on this drive to be indexed in addition to file properties.
    4. Click OK.

    Enabling Record Caching

    You should also check that record caching is enabled on the disk. When this feature is enabled, Windows 7 does not flush changed data to disk until the system is free, which naturally improves performance. The only drawback is that if there is a power failure or serious system failure, the data will remain unwritten to the disk, i.e. All changes made are lost. However, the likelihood of such situations occurring is minimal, so it is recommended to leave the record caching function enabled, which is what it is in Windows 7 by default. To check if this is indeed the case, use the following steps.

    1. Click the Start button, type manager in the search box, and then click Device Manager in the list of search results.
    2. Expand the Disk Devices node.
    3. Double-click the desired hard drive to display its properties sheet.
    4. On the Policy tab, make sure that the Allow entry caching for this device option is checked.
    5. To receive maximum performance check the box next to Disable cache buffer flushing Windows entries for this device. (It is important to note that this option is only available on certain hard drives who support it.)
    6. Click OK.

    Enabling the Turn off Windows record cache buffer flushing for this device option tells Windows 7 to use a more restrictive record caching algorithm. However, an unexpected power outage in this case will almost certainly result in data loss. Therefore, you should only enable this option if there is a source on the system uninterruptible power supply.
