Expand USB Host Controller; Update driver. Double click on your USB driver in Device Manager. Then Click on Driver tab and select Update. Reference: Update drivers in Windows 10. Also, check for the latest available drivers directly from the manufacturer's website. Windows has in built Driver Verifier as well to identify problematic. Standard SATA AHCI Controller drivers for Windows 10 Intel: Similarly, if you have an Intel computer and want to update the AHCI driver, then you can get them from this download link. If you are not able to the latest driver online, then this driver will certainly work for you as it is the standard version. To use this driver, download and run the.exe file on a PC running Microsoft Windows. The installer will request a destination folder; enter the path to a USB memory key. Then use that USB memory key to support the installation of Windows 7 or Windows Vista on the target PC.

Intel SATA Controller AHCI Driver For Windows 10 (64-bit), 8 ...

Summary :

You may wonder about the reasons for enabling Advanced Host Controller Interface (AHCI) in Windows 10. In this post, MiniTool shows you the reasons and how to enable AHCI after Win 10 installation.

What Is AHCI?

For many general users, AHCI is a strange term. But it is necessary to learn about this term due to the quick development of hard disk.

Short for Advanced Host Controller Interface, AHCI is an Intel technical standard that specifies the operation of SATA host bus adapters.

The top benefit of enabling AHCI mode for hard disk is that the disk can run at a higher speed than the disk adopting IDE mode. In other words, the performance of the hard disk will be greatly reduced if not using this mode.

Further reading:

AHCI and IDE are two modes. Under one of the modes, a hard drive communicates with the computer system adopting a SATA storage controller.

Basically, IDE is for average computer uses and is the most compatible with other technology, especially older devices. But it lacks support for new technologies. While AHCI supports some important new features that IDE dies not, like hot-plugging hard drives, Furthermore, AHCI offers an improved performance over IDE.

The reason why the disk performance can be improved by enabling the AHCI mode is that using this mode can greatly minimize the travel of data seek (the read/write speed of a SATA hard drive can be increased by about 30%). So, you can effectively use your hard disk under multitasks after enabling AHCI.

This article explains how to measure disk performance and how to interpret the disk performance test result. It touches upon terminology like IOPS, transfer rate, sequential reading/writing, random reading/writing, and queue number.

Till now, you may be eager to know to enable AHCI. But please note that you need to set up AHCI mode in BIOS before installing Windows. But cheer up even if you have finished Windows 10 installation. There is also some chance to enable AHCI after Windows 10 installation. Let’s see how to do that.
