In Windows 8, Windows 8.1 and Windows Server 2012, the controller driver has changed from msahci to storahci, [10] and the procedures to upgrade to the AHCI controller is similar to that of Windows 7. [11] On Windows 8, 8.1 and Windows Server 2012, changing from IDE mode to AHCI mode without first updating the registry will make the boot drive ...
Both modes work with SATA drives. The boot mode choice, with one mode or the other, is chosen in modern BIOS/UEFI after driver installation. [3] Once one or the other driver is installed, it is not possible for the Windows operating system to boot again with the BIOS/UEFI set to RAID/IDE, producing BSOD in case of trying. [4]
When enabled via the AHCI controller, this allows the SATA host bus adapter to enter a low-power state during periods of inactivity, thus saving energy. The drawback to this is increased periodic latency as the drive must be re-activated and brought back on-line before it can be used, and this will often appear as a delay to the end-user.
It often implements hardware RAID, thus it is sometimes referred to as RAID controller. It also often provides additional disk cache . Disk array controller is often ambiguously shortened to disk controller which can also refer to the circuitry responsible for managing internal disk drive operations.
[4] [5] Linux kernels support AHCI natively since version 2.6.19, and FreeBSD fully supports AHCI since version 8.0. Windows Vista and Windows 7 also natively support AHCI, but their AHCI support (via the msahci service) must be manually enabled via registry editing if controller support was not present during their initial install.
In 2008, Hard Disk Sentinel DOS version was released in different formats on bootable pen drive, CD, floppy. Usable when no operating system installed (or if the system is not bootable otherwise) to detect and display temperature, health status of IDE, SATA hard disk drives and with limited AHCI controller support.
Supports Pentium 4 on an 800 MT/s bus. Uses DDR memory up to 400 MHz, or DDR2 at 533 MHz. Replaces AGP and CSA with PCI Express, and also supports "Matrix RAID", a RAID mode designed to allow the usage of RAID levels 0 and 1 simultaneously with two hard drives. (Normally RAID1+0 would have required four hard drives)
In computer data storage, Smart Response Technology (SRT, also called SSD Caching before it was launched) is a proprietary caching mechanism introduced in 2011 by Intel for their Z68 chipset (for the Sandy Bridge–series processors), which allows a SATA solid-state drive (SSD) to function as cache for a (conventional, magnetic) hard disk drive (HDD).
