Which is faster ahci or ide. AHCI or IDE - which is better and what is the difference
Where was it mentioned that for her normal operation AHCI mode is required. This mode unleashes the full capabilities of storage devices, which greatly improves performance. We are talking about memory storage devices - SSD, HDD. Next, you will find out what AHCI is, let’s check whether it is enabled, and if not, then enable it.
What is AHCI?
Previously, computers had the so-called PATA interface, to which all storage devices were connected, but its days have passed and it has been replaced by SATA interface, which will be discussed now.
SATA has two operating modes:
IDE(Integrated Development Environment) – this mode needed to create compatibility with outdated devices, which are still connected via the PATA interface, which can be said that the SATA interface with IDE mode is almost the same as PATA.
AHCI(Advanced Host Controller Interface) is a SATA mode that reveals all the capabilities of memory drives. It has several interesting features: hot plugging and hot plugging hard drives, that is, you can do this while the computer is turned on. Another possibility is NCQ technology, which reduces the number of read head movements of hard drives and also improves drive performance.
Using this mode will have a positive effect, in practice it is not that noticeable, to be honest, but still, there is something, so I would recommend turning on this mode if it is turned off, especially since there is nothing complicated about it.
Does your computer have AHCI mode?
There are two ways to find out if there is an AHCI mode on a PC or laptop; if you have it quite new, then most likely you have it.
First method : We have to go to Device Manager where you expand the tab IDE ATA/ATAPI controllers, or something similar, and if the controller name contains the word AHCI, then this mode is used.
Second method : The presence and use of AHCI mode can be viewed and. There you should find SATA mode, or something similar and check what is there, if AHCI, then you can rest assured.
I would like to remind you that instead of the AHCI item there may be IDE, but you should not immediately switch this mode, below you will find out why.
How to enable AHCI mode in the operating system?
AHCI is enabled through the BIOS. Most likely, you have motherboard There are SATA interfaces, but you cannot activate the AHCI function in the BIOS. Most likely the problem is in the BIOS firmware, and it needs to be updated, but this should not be done without special knowledge.
If you have modern versions Windows, then you already have the AHCI driver installed, it is required. It's built in from Windows Vista. In this case, you can activate AHCI without any problems.
What to say about Windows XP, at that time there was no AHCI mode yet, and the SATA interface was just being developed. But the necessary driver can be found on the Internet and used in Windows XP.
That's all, I told you about the features of the AHCI mode, now you know how to check for its presence and how to enable it.
It is advisable for every user who would like to significantly expand and at the same time improve the capabilities of their PC for working with hard drives to configure and enable special AHCI mode SATA type, as well as SSD.
This mode makes it possible to significantly speed up your PC due to its improved data access speed, and to activate this mode, you just need to perform a few basic steps.
1. AHCI is
A special interface of modern SATA hard drives, which support data transfer rates from one and a half to six gigabits, and its operation is possible in two modes:IDE and AHCI.
IDE– will ensure compatibility with older drives that were produced in the 2000s. AHCI– provides the user with the opportunity to fully use the entire SATA interface. For example, this will help to disconnect or connect the disk to the “motherboard” directly during operation, without even turning off the PC, or with the possibility of minimal movement of the disk heads, thereby increasing its speed.
After activating the mode, the user will significantly speed up working with files, writing them and reading information on the hard drive, which will significantly increase the performance of the PC as a whole. The increase will be approximately 20 percent, but nevertheless, for some demanding tasks, this twenty percent will be quite enough.
If you are working with SSD drives and the SATA form factor, then the option of enabling AHCI is the only correct and possible one.
2. Check AHCI mode. Enabled or not.
Before enabling AHCI Mode, you should make sure that it is not already in use. If you often work with heavy applications, your PC is equipped with powerful modern processor and a sufficient amount of memory, then you simply will not notice in which at the moment mode your PC is working.Checking AHCI mode:
1. Go to “Computer” properties;
2. Open the device manager;
3. Find IDE ATA/ATAPI controllers;
4. If some name contains AHCI, then the mode is active. If there is no such mode, then it needs to be enabled.
There is another way to check for the presence of AHCI - reboot the PC and view this parameter through the BIOS. You probably already know how to enter BIOS.
Going to BIOS, UEFI– look in what mode SATA operates, this can be done in the section SATA Mode, or SATA Configuration.
3. How to enable AHCI mode
Enabling the mode AHCI, most often, is performed through .But, if you are on Windows 7, then after loading the system, an error may appear on your screen indicating incompatibility with the hard drive. A similar situation can happen with other, newer operating systems, but with less probability. In case of an error, the computer will reboot or restart.
If you select AHCI-mode before installation new system- the situation will change. This will allow the software from the disk to adapt, which ultimately will not lead to any problems.
Typically, difficulties arise when the system is already on the hard drive, and the user changes the SATA settings to IDE, or vice versa, and tries to turn on NCQ– protocol SATA, which will significantly speed up work with information due to improved command optimization. In this case, interaction with various registry editors will be required. If nothing has provided the desired result, then AHCI mode can be installed only after reinstalling the system.
AHCI for Windows 7
Windows 7 – also most often requires switching the mode to AHCI. To do this, try the following:
1. Enter Registry Editor. This is done through the “Run” menu by entering the following command into it: regedit.
2. Find and go to the section HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\msahci;
3. Click on “Start”, while changing the standard value 3 to 0.
4. In the same subsection, change msahci to lastorV, and look for Start parameter;
5. " 3 " change to " 0 »;
6. We finish working with the editor.
Reboot the computer and enable the required mode via BIOS. After loading Windows 7, drivers for drives connected to the motherboard will begin to be automatically installed on the PC. After installed drivers And changes made you will need to restart your PC again. The final stage in editing the mode is checking the “cached” recording mode. This is done in the disk properties. If caching is not activated - it needs to be launched.
Microsoft Fix it – additional option getting rid of errors after installing a new mode. After the new mode has been launched and enabled. After selection necessary actions and troubleshooting, the software will automatically make all changes, and subsequent errors will not appear.
AHCI for Windows 8 and 8.1
If you have eight on your PC, to enable AHCI mode, you need to go to safe mode. And in case of errors, is it necessary?
1. Change the IDE mode in the BIOS;
2. Restart the PC;
3. Go to launch the command line;
4. Enter the following command: bcdedit /set (current) safeboot minimal;
5. Confirm the action;
6. Reboot the PC and enter the BIOS again;
7. Activate the required AHCI mode;
8. Launch the command line again;
9. Enter bcdedit /deletevalue (current) safeboot;
10. Reboot the system again, after which Windows will display an error.
If the system is on an Intel processor, then AHCI can be enabled using additional utilities from the manufacturer itself. AMD does not have this method.
To use it, you need to do the following:
1. Download the file from the official Intel website f6flpy;
2. Download here SetupRST.exe
3. Go to the device manager and install the special f6 AHCI driver manually in the hard drive properties, instead of the specified SATA one;
4. Restart the PC, go to BIOS and enable AHCI;
AHCI for Windows 10
To correct errors or switch modes, you can also use the program of the same name for Intel processors; this can be done using: reinstalling windows, and through safe mode. But the best option will use the registry editor, which is slightly different from standard method, which was specified in Windows 7.
You will need:
1. Log in as “Administrator”;
2. Launch Registry Editor in an accessible way(for example, using the “Run” utility, entering regedit into it;
3. Go to a special section HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\iaStorV, where you will need to find “Start”, and change the parameter value to “ 0
»;
4. Find in another subsection Services\iaStorAV\StartOverride parameter called 0, and set its value to “0”;
5. Now choose Services\storahci, completely reset the “Start” parameter;
6. In the next subsection Services\storahci\StartOverride, setting the parameter value to “0”;
7. Close the editor and restart the computer;
8. Enter the BIOS and also enable the required mode AHCI.
Advice: The first one is best Windows startup 10 run in safe mode, and to do this, turn it on using the “Run” menu by entering the msconfig command into it in order to display all system settings. Select the “Boot” tab and check the “safe mode” box, selecting the “Minimal” option.
If instead of BIOS you have UEFI– you need to troubleshoot through the system menu.
1. Enter the menu (Win+l);
2. Enter “update and security”;
3. We enter “recovery”, and then move on to special options downloads;
4. Go to special menu, located in the tab " Additional options", and as a result, go to the section " UEFI Settings».
To go to the BIOS settings, you can press a specific key to go to the BIOS - this could be the F2, F12 or other buttons.
4. Other AHCI Features
For Windows XP there is no option to install AHCI. At the time of its development, this option was not intended or planned. If you want to do this, then find a special driver and implement it into the system. But I strongly do not recommend doing this; such a possibility can have a bad effect on the operation of the system.Winodws vista included an identical switching mode AHCI, as in Windows 7, that is, using a utility or registry.
5. Results
Most often, after completing the steps to set the mode AHCI, the system will work stably, plus accelerated. If nothing works, then you can reinstall the system again after the mode change has occurred - this may take quite a bit of time, but the result is most often guaranteed.SATA RAID/AHCI Mode
Possible values:
Disabled, RAID, AHCI
Description:
The option allows you to specify the operating mode of a modern IDE/SATA chipset controller. When value Disabled To access SATA drives, a mechanism similar to a conventional IDE controller will be used. Of course, this somewhat limits the performance of the disk subsystem, but you do not need to install additional drivers - everything you need is already included in any operating system.
Meaning RAID found only on motherboards that support RAID arrays of drives connected to a standard IDE/SATA chipset controller. His choice makes it possible to combine hard drives into RAID arrays in order to increase the reliability of information storage or to increase the speed of operation. Just keep in mind that when installing the Windows 2000 or Windows XP operating system, you will definitely need a diskette with drivers (if your computer does not have a disk drive, this may lead to an unresolvable problem, since other drives are not supported). Drivers are also required for Windows Vista, but in this case, in addition to a floppy disk, they can also be written to a CD or Flash drive.
Naturally, you can only talk about a RAID array if you have two or more installed on your system. hard drives. Moreover, it is desirable that they be of the same brand and volume, ideally with the same firmware and from the same batch.
Meaning AHCI present only on fairly new motherboards whose IDE/SATA controller supports the SATA II interface. Selecting this option allows you to take advantage of all the benefits of the Advanced Host Controller SATA II (AHCI stands for Advanced Host Controller Interface) - command queuing, hot plugging, etc. We should not forget about the higher performance of the disk subsystem in this mode. If your hard drives support SATA II, it makes sense to choose this value. Just keep in mind for Windows installations 2000 or Windows XP you will need a driver floppy disk.
For older operating systems ( Windows family 9x), using RAID arrays and an AHCI controller is hardly possible - the necessary drivers simply do not exist.
It is necessary to change the operating mode of the standard IDE/SATA chipset controller before installing the operating system. If the system is installed, simple change mode in the BIOS will cause " blue screen death." If you still want to enable AHCI on installed system, before changing the value of this option, force change the IDE/SATA controller driver to the desired one.
Proper operation of a computer is possible only with coordinated interaction between the hardware and the operating system. Technologies are developing and lately This is most noticeable in the area of storage. Modern hard drives and SSD drives are many times faster than those used in computers 5-10 years ago. For data transfer, the SATA interface is used, through which the drive is connected to the computer. The SATA interface is capable of operating in two modes: IDE and AHCI, and if you have a modern hard drive or SSD, you can speed up your computer by enabling AHCI mode.
What is AHCI mode
As noted above, AHCI is one of the data transfer modes over the SATA interface. As you know, through the SATA interface you can transfer information at speeds from 1.5 to 6 Gigabytes per second. Maximum speed is supported specifically in AHCI mode, which should be used with all modern drives. Regarding IDE mode, it is supported in the SATA interface for compatibility with older hard drives.
Default in operating system Windows does not always enable AHCI mode, even if the drives are connected to the motherboard via SATA. Because of this, the user loses in computer performance, since the disk speed is limited by software. By setting the AHCI mode, you can increase the speed of the drive by 20-30%, which will affect the overall experience of the computer.
How to find out if AHCI mode is enabled in Windows
Most often, users do not even suspect that it is necessary to enable AHCI mode in order to improve computer performance. At the same time, Windows by default does not always work with HDDs and SSDs, even the most modern ones, in AHCI mode. To check if AHCI mode is enabled in Windows, you need to do the following:
Please note: Also, the absence of devices operating in AHCI mode in the list may be due to the fact that old drives that are not capable of operating in the new mode are connected to the motherboard.
You can also check whether the SATA interface works in AHCI or IDE mode through the BIOS. To do this, you need to restart the computer and press “Del” or F2 during the boot process. The BIOS will launch, where you will need to find the SATA Mode item and see whether the AHCI or IDE option is installed.
Important: If you notice in the BIOS that the SATA interface is set to work in IDE mode, you do not need to switch to AHCI mode, since this will not do any good.
How to enable AHCI mode in Windows
Microsoft began supporting AHCI mode in Windows operating systems with Windows 7. However, you can enable it in Windows XP if you download necessary drivers on the Internet, made by enthusiasts, and install them. However, it is worth noting that this method does not always give a performance boost, and on Windows XP it is better to abandon the idea of using AHCI mode and work with drives through a standard IDE.
To enable the AHCI mode itself, just set the appropriate setting for SATA in the BIOS. But this must be done before installing the Windows operating system, otherwise when booting the computer will display error 0x0000007B INACCESSABLE_BOOT_DEVICE or go into the constant reboot. Therefore, to switch IDE mode to AHCI when installed Windows, you need to make some changes to the registry; below we will look at what actions to perform for each version of the operating system.
How to enable AHCI mode in Windows 10
In a modern operating room Windows system 10, Microsoft did not offer a setting that would enable support for AHCI mode on the fly if the SATA interface was previously running via IDE. To correctly switch to AHCI mode, you will need to do the following:
After the computer boots, the Windows operating system will prompt you to install the necessary drivers to work with AHCI mode; be sure to do this.
How to enable AHCI mode in Windows 8 and Windows 8.1
To switch the Windows 8 or Windows 8.1 operating system to work with AHCI mode, you need to do some work in command line. You will need to do the following:
It is worth noting that if the computer runs on an Intel CPU, then you can use standard utility company that allows you to make the necessary settings for switch Windows to work with AHCI. This is done as follows:
Please note: The above method is only suitable for computers with Intel processors, for AMD such a decision not at the moment.
How to enable AHCI mode in Windows 7
In the Windows 7 operating system, the method for enabling AHCI mode is close to that used in Windows 10. Here you will also need to make some changes to the registry as follows.
Hello everyone, I would like to tell you which mode to choose correctly for hard drive so that it works as it should.
Most likely, this article is suitable for medium-sized computers that may have the wrong option selected. But just in case, check. Before that, I also somehow didn’t think about it until my director told me.
In general, closer to the point) First you need to go into the BIOS of your computer. On different versions BIOS has different login buttons, usually del on computers and F2 on laptops. When the computer boots, it usually says press F2 (Del) for bios. Just in case, here's a hint:
How to enter BIOS in different versions:
On your computer:
On a laptop:
Once you have logged in, you need to look for the Sata Configuration parameter. In it you need to select AHCI mode.
At the same time, I’ll tell you what these modes are:
There are ways IDE connections and SATA:
IDE mode
The IDE (Integrated Development Environment) connector is an outdated connector (developed in the 80s), as can be seen in the picture, it was previously used for connecting hard disks, floppy drives, cidiroms, etc. which supported such connectors. In those days, of course, this connector was incredibly popular, but now, of course, all that remains is to remember it and change it on old computers.
In addition to all this, even the cords themselves are more convenient and take up less space. The sat connectors support HotSwap and HotPlug i.e. hot replacement, which is convenient in servers. No need to reboot or shutdown.
AHCI is a mode SATA connections devices, so I came to the solution to all the articles. Thanks to this mode sata devices work properly.
In order for all your devices to work well, you need to select it (of course, if you have not already selected it).
But first you need to choose windows mode achi otherwise Windows will not start! Of course you can try, but most likely... Therefore, I will show you how to install achi mode on Windows 7.
How to enable ACHI mode?
This is done using the registry.
Press start - run (or WIN + R).
Type regedit and press enter.
The Registry Editor will appear. In it we follow the path:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\msahci
