Ryzen provides two different SATA controllers. Both export a standard SATA driver interface and work without custom drivers, but only one of them works with the AMD 2015 driver. The AMD driver doesn't actually seem to bring any benefits over the default driver. SATA AHCI is basically a controller mode in the BIOS of your computer. As the name suggests, it basically controls all the storage drives of your computer with AHCI protocols. This means that if you are using SATA AHCI controller, you will be able to use all the features of AHCI mentioned above.

I am looking for an updated driver for the 'Standard SATA AHCI Controller' on my Intel NUC8i5BEK. The current driver is 'storahci.sys' and is dated 2006-06-21. I have tried looking for a driver update with no success. I have had repeating blue screens of death on this so-called new computer, with ex. Intel® Rapid Storage Technology (Intel® RST) supports the following Intel® Chipsets and Controllers. Intel ® 8th Generation Core Processor Family Platform I/O SATA AHCI/RAID Controller Intel® 300/240 Series Chipset Family: Desktop, High End Desktop, Workstation. Purpose Installs the Intel® Rapid Storage Technology (AHCI) driver version 12.9.0.1001 for Intel® NUC. Which file to choose Download the driver (STORWin788.112.9.0.1001.exe) and one of the following F6 Driver Diskettes (depending on your operating system):STORWin788.112.9.0.1001f6flpy-x86.zip - for 32-bit versions of the operating system.

Whatever storage driver is in the system, has a connection to SATA AHCI Controller. These controller drivers are an essential component of the system as without them, you’d start experiencing trouble accessing PC drivers. It is also crucially important to keep the standard sata ahci controller driver windows, 10 drivers, up to date to avoid any early corruption of the driver.

That being said, here’s what is the troublesome aspect. Users fail to find the correct driver specific to the system. Hence, you’re looking at a guide on ho you can get the most out of SATA AHCI Controller.

SATA AHCI: What is it?

SATA is also known as Serial Advanced Technology Attachments. It serves the purpose of working with all the drivers for storage use. In order to make the drivers of the system make efficient, SATA 3 protocol is used. However, it is much different from the function of the IDE. As IDE works on signaling in a parallel way, SATA works ina serial order.

Also, it is much better than old technologies. This is because SATA provides relatively high speed for transferring files.

AHCI

AHCI is also known as the Advanced Host Controller Interface. AHCI acts like a messenger between the SATA and the drivers of the system. T rather serves the purpose of communication among the two.

If you’d like to enable the AHCI mode, then you can use the UEFI BIOS mode from the system.

Here’s an interesting fact why HCI is quite useful than you can imagine. You can swap the drivers of the system using the AHCI mode. Also, AHCI gives you that ultimate speed. This is why Windows 10 run time speed is relatively fast.

How is AHCI Different from IDE Mode?

As many users have been wondering the key difference between IDE and AHCI, then here’s where the line is drawn:

AHCI is different from IDE because it has an ability called hot-swapping. This ability basically is that without having to switch off the system, it allows any user to replace the drivers of the disk.

Also, AHCI has something that IDE does not have. And that is command queuing.

Command Queuing is known to deliver fast speed which AHCI provides, unlike IDE. This is the reason why most users prefer using SATA instead of using ATA.

How to Know if the System has SATA Mode?

If you’re curious about finding out the SATA controller that is being used by the system then follow these steps below:

Open the Quick Menu using the Windows and the “X” key on the keyboard. From the following window, go to the option called “Device Manager”. Then, locate the program called “IDE ATA/ATAPI Controller”. Expand the program file selected.

In the following lists, if you see a file named “Standard SATA AHCI Controller” then be sure that the system is, in fact, being run on the AHCI Mode.

Is it Possible to Switch From SATA to AHCI?

If you are wondering if you can switch from SATA to ACI then most certainly you can. Here’s how to do it standard sata ahci controller:

At first, you need to restart the Windows 10 system. However, there’s one thing to keep in mind. This process is not advisable if you already have the Windows 10 OS installed on the PC. It is only applicable if you plan on installing wIndows 10 from fresh again. Otherwise, you’d end up getting a blue screen with the following error code:

“INACCESSIBLE_BOOT_DEVICE”

Now, let us begin,

First, restart the system and when you are restarting it, make sure you’re using the Delete key until you enter into the BIOS mode.

Then, in the following BIOS Mode window, search for the option called “Advanced”. Or you could look for the file called “Standard/Storage Configuration”.

Now you’ll find a file called SATA Configuration. Or it can also be named as “SATA Controller Settings”.

Then, choose the option called “Configure SATA” and then select the option called “AHCI”.

Then press the “F10” key in order to save the settings that you’ve just made. After that, the system will reboot. Allow the process to finish and then you’d have AHCI mode activated from STAA IDE.

How to Install Drivers for SATA AHCI?

So “how to update standard sata ahci controller”? As of now, you must be well aware of SATA AHCI Contoller’s importance. This is because it provides the communication purpose between the system’s motherboard and Windows 10 operating system.

So, if these drivers get damaged or corrupted for some reason, it could potentially cause the system to develop issues such as lagging or response time being very slow. For this reason, it is always advisable that you update the SATA AHCI Drivers.

Before you can begin standard sata ahci controller update driver, it is advisable that you download the latest version for either AMD or Intel. Here’s how to do it:

1. SATA AHCI Controller: [AMD]

To get SATA Controller, in the AMD, here’s what you can do. Lookup Controllers based on AMD computers. Download it and install it right away for standard sata ahci controller driver update:

2. SATA AHCI Controller: [INTEL]

For Intel Computers, you can do the same process. Simply lookup for the SATA AHCI controller compatible with the Intel system.

Here’s how you can Update SATA AHCI Controller Driver

Once you have downloaded the newest version of the SATA AHCI controller driver, you can now begin to update the driver for a better output. And there are generally two ways you can do that:

1. From Installation File

You can update the driver from the installation files. When you download the driver, go to the location where the file driver was downloaded. In that folder, you’d see a file that ends with “.exe”. Click on that file and your driver will be updated to its latest version.

2. From Device Manager

Here’s another way you can update the driver. And that is, from Device Manager.

At first, go to the “Start” menu and type “device Manager” in the search bar. Or you can simply launch “Device Manager” using the “Windows” and the “X” key.

Now in Device Manager, locate the file called “IDE ATA?ATAPI Controllers”. Expand the file and you’ll see the program called “SATA Controller”. Then, right-click on the driver and select the option called “Update Driver”.

In the following window, choose the option called “Search Automatically for updated driver software”. Now te driver will be updated.

The Advanced Host Controller Interface (AHCI) is a technical standard defined by Intel that specifies the operation of Serial ATA (SATA) host controllers in a non-implementation-specific manner in its motherboard chipsets.

The specification describes a system memory structure for computer hardware vendors to exchange data between host system memory and attached storage devices. AHCI gives software developers and hardware designers a standard method for detecting, configuring, and programming SATA/AHCI adapters. AHCI is separate from the SATA 3 Gbit/s standard, although it exposes SATA's advanced capabilities (such as hot swapping and native command queuing) such that host systems can utilize them. For modern solid state drives, the interface has been superseded by NVMe.^[1]

As of December 2019, the current version of the specification is 1.3.1.

Operating modes[edit]

Sata Ahci Controller Driver Dell

Many SATA controllers offer selectable modes of operation: legacy Parallel ATA emulation (more commonly called IDE Mode), standard AHCI mode (also known as Native Mode), or vendor-specific RAID (which generally enables AHCI in order to take advantage of its capabilities). Intel recommends choosing RAID mode on their motherboards (which also enables AHCI) rather than AHCI/SATA mode for maximum flexibility.^[2] Legacy mode is a software backward-compatibility mechanism intended to allow the SATA controller to run in legacy operating systems which are not SATA-aware or where a driver does not exist to make the operating system SATA-aware.

When a SATA controller is configured to operate in IDE Mode, the number of storage devices per controller is usually limited to four (two IDE channels, master device and slave device with up to two devices per channel), compared to the maximum of 32 devices/ports when configured in AHCI mode.^[3][4] But the chipset SATA interfaces may emulate more than one 'IDE controller' when configured in IDE Mode.

Operating system support[edit]

AHCI is supported out of the box on Windows Vista and later, Linux-based operating systems (since version 2.6.19 of the kernel), OpenBSD (since version 4.1), NetBSD (since version 4.0), FreeBSD (since version 8.0),^[5]macOS, ArcaOS,^[6]eComStation (since version 2.1), and Solaris 10 (since version 8/07).^[7]DragonFlyBSD based its AHCI implementation on OpenBSD's and added extended features such as port multiplier support. Older versions of operating systems require hardware-specific drivers in order to support AHCI. Windows XP and older do not provide AHCI support out of the box.

System drive boot issues[edit]

Some operating systems, notably Windows Vista, Windows 7, Windows 8, Windows 8.1 and Windows 10, do not configure themselves to load the AHCI driver upon boot if the SATA controller was not in AHCI mode at the time the operating system was installed. Although this is an easily rectifiable condition, it remains an ongoing issue with the AHCI standard.

The most prevalent symptom for an operating system (or systems) that are installed in IDE mode (in some BIOS firmware implementations otherwise called 'Combined IDE mode'), is that the system drive typically fails to boot, with an ensuing error message, if the SATA controller (in BIOS) is inadvertently switched to AHCI mode after OS installation. In Microsoft Windows the symptom is a boot loop which begins with a Blue Screen error, if not rectified - and through no fault of Microsoft Windows.

Technically speaking, this is an implementation bug with AHCI that can be avoided, but it has not been fixed yet. As an interim resolution, Intel recommends changing the drive controller to AHCI or RAID before installing an operating system.^[2] (It may also be necessary to load chipset-specific AHCI or RAID drivers at installation time, for example from a USB flash drive).

On Windows Vista and Windows 7, this can be fixed by configuring the msahci device driver to start at boot time (rather than on-demand). Setting non-AHCI mode (i.e. IDE or Combined mode) in the BIOS will allow the user to boot into Windows, and thereby the required registry change can be performed. Consequently, the user then has the option of continuing to use the system in Combined mode or switching to AHCI mode.^[8]With Windows 10, this can be fixed by forcing the correct drivers to reload during Safe Mode.^[9]

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 SATA mode to AHCI mode without first updating the registry will make the boot drive inaccessible (i.e. resulting in a recurring boot loop, which begins with a Blue Screen error).

Microsoft Standard Ahci Driver Download

In Windows 10, after changing the controller to AHCI mode, if the OS is allowed to reboot a couple of times after the start of the boot loop, which starts with an INACCESSIBLE_BOOT_DEVICE BSOD, Windows presents recovery options. Out of the Advanced options, if Startup Repair option is selected, Windows attempts to fix the issue and the PC begins to function normally.

A similar problem can occur on Linux systems if the AHCI driver is compiled as a kernel module rather than built into the kernel image, as it may not be included in the initrd (initial RAM disk) created when the controller is configured to run in Legacy Mode. The solution is either to build a new initrd containing the AHCI module, or to build the AHCI driver into the kernel image.^[12]

Power management[edit]

Power management is handled by the Aggressive Link Power Management (ALPM) protocol.
