The AHCI is a standard technical term, and Intel defines it.

Its a register-level interface ofSATAhost controllers in a non-implementation-specific manner within the motherboards chipset.

However, IDE is the older interface to transfer data between the system memory and the storage drive.

It also doesnt support modern technologies.

But AHCI is the latest interface and is compatible with modern high-end storage technologies likeRAID.

Its conveniently faster than the traditional IDE interface.

AHCI supportshot-swappinghard drives andNative Command Queuing (NCQ), whereas IDE lacks all of these features.

With hot swapping, you dont need to shut down the computer to swap out the SATA drive.

NCQ helps to improve the performance while transferring large files on SSDs.

after you snag enabled the AHCI mode, the hard drive will run faster than the IDE mode.

So, lets see how to enable AHCI mode in Windows 11.

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\iaStorV

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\iaStorAVC\StartOverride

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\storahci

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\storahci\StartOverride

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\iaStorAV\StartOverride

After the reboot, Windows will automatically start installing AHCI drivers.

Once all the drivers are installed successfully, youll see a prompt for restarting the PC.

So, restart the PC, and you are good to go with the AHCI mode turned on.
