Same with the Marvell driver, in my opinion.
Windows 10 serial ata controller driver driver#
The reason is that the driver works just fine and no further modifications to it have been necessary. It being Jan 2021, a newer version would be expected. Updates to the driver usually address support for a slightly modified chip.įor example, if you look in Device Manager at the standard Microsoft-supplied "Disk drives" driver, it's from.

One always hopes that newer drive controller drivers will increase the drive speed a little. WHQLĪccording to the file version number, it is numbered higher so naturally it should be a newer version However, as I mentioned, finding this driver isn't easy and I ran across several that, no matter the date or version number, simply wouldn't work. Marvell MV-91xx/92xx SATA 6G Controller Version 1. Specifically, NVMe significantly increases the number of I/O queues possible with queue depths of as much as 65,000.The latest driver I can find is marvell_mv91xx_1. Nonvolatile memory express ( NVMe) is a communication interface developed for NAND flash and high-performance SSDs using PCI Express ( PCIe) card slot technology.īecause it was specifically developed for SSDs, NVMe is much faster than AHCI, reduces latency and provides better IOPS. Additional management is required to avoid having I/O requests fail because they exceed the queue depth. Also, AHCI's limited queue depth means the number of I/O requests can easily become a bottleneck. One downside to AHCI is high latency when it is used with SSDs because the specification was developed for rotating storage media and not flash. On SSDs, NCQ improves the performance of large file transfers. NCQ optimizes the way SSDs and hard drives handle simultaneous requests for data, minimizing the movement of the read-write heads and speeding up access time on hard drives using AHCI. Hot swapping enables SATA drives to be switched out without having to shut down the computer. Benefits and drawbacks of AHCIĪHCI enables advanced SATA features, such as hot swapping and Native Command Queuing (NCQ). For AHCI, this queue has a depth - the number of I/O requests that can be kept waiting to be serviced in a port queue - of 32 commands. Older OS versions require hardware-specific drivers to support AHCI.Īs a traditional storage protocol developed for hard drives and tape, AHCI was designed to manage a single storage request queue.

Windows has a registry workaround that will allow AHCI to be enabled after the OS is installed. However, it isn't easy to switch the BIOS setting from IDE mode to AHCI once the OS is installed.
SATA hard drives and solid-state drives (SSDs) offer several modes of operation: IDE, AHCI or RAID, which usually has AHCI enabled.

While Windows Vista and Windows 7 include the AHCI driver, those OSes won't install AHCI if it's not enabled on the boot drive's controller. Older motherboards may have IDE mode enabled by default and would need to be switched to AHCI before the operating system (OS) is installed.ĪHCI is supported on Windows Vista and later versions of Windows Linux since version 2.6.19 OS X and various open source operating systems, such as OpenBSD, NetBSD and FreeBSD. Most motherboards have AHCI enabled by default in the Unified Extensible Firmware Interface ( UEFI) or BIOS. Version 1.3.1 is the most recent iteration of the AHCI specification. Companies in the group included AMD, Dell, Marvell, Maxtor, Microsoft, Red Hat, Seagate and StorageGear.ĪHCI was an important part of building momentum for SATA II technology, providing a standard controller interface that optimizes advanced SATA features that weren't available with the older Integrated Drive Electronics ( IDE) standard interface.

The specification was developed by the AHCI Contributor Group, which was comprised of hardware, software and OEM vendors, and was chaired by Intel. The specification also provides a standard way to program SATA-AHCI adapters. In 2004, Intel released the AHCI specification to define the functional behavior and software interface of AHCI. These peripheral component interconnect (PCI )-class devices move data between system memory and SATA storage media.
