AMD Unveils New RAID Driver: Enhancements and Support Details
In a recent development, AMD has launched a significant update to its RAID driver, now at version 9.3.3.00117. This update is part of a comprehensive RAID installer software package, labeled version 6.10.09.200, which is compatible with both Windows 10 and Windows 11. A key highlight of this release is the added support for Windows 11 version 24H2, alongside the introduction of Host Memory Buffer (HMB) support, allowing advanced functionality when RAID is enabled on NVMe SSDs.
Understanding SSD Technology: DRAM Cache and HMB
To fully appreciate this update, it’s important to note the functioning of SSDs. Many SSDs incorporate a dedicated DRAM chip that serves as a cache for metadata exchanged between the controller and NAND flash memory. The presence of this cache significantly enhances write speeds and minimizes random access times. In contrast, NVMe SSDs lacking a DRAM cache utilize HMB technology, which enables the controller to access system memory through Direct Memory Access (DMA).
What is RAID?
RAID, or Redundant Array of Independent Disks, is a storage technology that combines multiple disks to enhance data redundancy and performance. By utilizing a RAID setup, users can prevent data loss while also potentially improving overall system speed, making it a vital tool for both personal and professional data management.
New Features and Improvements
The latest RAID driver offers various enhancements and fixes, along with the exciting new features. Key updates include:
- Compatibility with Windows 10 and 11.
- Updated AMD RAID driver (9.3.3.00117) and RAIDxpert2 utility (9.3.3.00117).
- Support extended for Windows 11 24H2.
- Resolution for random BSOD occurrences.
- Enabling of NVMe HMB support within the RAID driver.
- The update requires two consecutive system reboots for proper functionality; the installer manages this automatically.
Known Issues and Limitations
While the driver showcases several enhancements, several known issues and limitations must also be considered:
- OS installation may fail if the OS is not located on the primary RAID array.
- RaidXpert2 application may fail to open if the OS username includes non-Latin characters.
- Removing NVMe drives during active IO operations is not advisable.
- NVMe removal from front bays post-array transformation may lead to failures.
- The RAIDxpert2 application may become unresponsive after array changes or when reattaching removed NVMe drives.
- Installation of the RAID package can take approximately 3-4 minutes.
- Post-installation experiences may vary, particularly regarding consecutive reboots when switching user accounts.
