Improve hard disk performance SATA disks can work both in a way that they only use the functions of the PATA disks as always, and, in the plates with Intel chipset, in a mode (AHCI, Advanced Host Controller Interface) in which has access to new features of SATA disks to Improve hard disk performance. The AHCI provides software developers and hardware designers with a standard method for detecting, configuring, and programming SATA / AHCI adapters. The AHCI is separate from the SATA 3Gbit / s standard, but exposes the advanced capabilities of SATA (such as hot swap and native command queue) so that host systems can use them.

Switch from IDE to AHCI and Improve hard disk performance

If you have installed your operating system with an IDE but want to install it with the AHCI, then you have to enable the AHCI on your computer to Improve hard disk performance. This tutorial will show you how to enable AHCI in Windows 10 if you have installed the operating system with an IDE by mistake.

Therefore, you must “take backup of Windows registry“.

To apply this Windows Features you should open Windows Registry Tool and browse the following Regedit path step by step or you can jump to target Windows Registry Tool with single click.

METHOD NO. 1

To apply setting of Switch from IDE to AHCI and Improve hard disk performance

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\pciide]
"Start"=dword:00000000

To Restore setting of Switch from IDE to AHCI and Improve hard disk performance

Copy the below code and save it as .reg, double click the saved file and accept all messages.

Windows Registry Editor Version 5.00
