    AMD Launches NVMe RAID Support on Thread Ripper

    Speed has been human’s long desire for generations. There is a need for speed in cars, networks, and of course storage.
    Previously, we were bottlenecked by the narrow DMI 3.0 bus at the peak performance of no more than PCIe 3.0 x4 (up to 4000MB/s), and now, it’s AMD’s turn to reveal its cards.

    Introducing AMD NVMe RAID for ASUS X399 platform, support up to 6x NVMe SSDs in the form of RAID 0/1/10.
    A few simple steps for massively impressive results.

    Benchmark Performance Released: IOMeter v1.1.0 x64 Perofmance (1MB / QD32 / RAW FS)
    1x NVMe SSD:
    - Read: Up to 3536MB/s
    - Write: Up to 2141MB/s

    2x NVMe SSD (RAID0):
    - Read: Up to 7074MB/s
    - Write: Up to 4181MB/s

    3x NVMe SSD (RAID0):
    - Read: Up to 10546MB/s
    - Write: Up to 6054MB/s

    4x NVMe SSD (RAID0):
    - Read: Up to 14027MB/s
    - Write: Up to 7992MB/s

    5x NVMe SSD (RAID0):
    - Read: Up to 17463MB/s
    - Write: Up to 9941MB/s

    6x NVMe SSD (RAID0):
    - Read: Up to 21220MB/s
    - Write: Up to 11532MB/s

    Testing conducted by AMD performance labs as of 9/18/2017. Test configuration: AMD Ryzen™ Threadripper™ 1950X, 4x8GB DDR4-3200 (16-16-16-36), ASUS ROG Zenith Extreme, 1-6x Samsung 960 Pro NVMe SSD (512GB ea.), default BIOS settings, Windows® 10 x64 RS2, NVIDIA GeForce GTX 1080 (driver 385.41), RAID Writeback Cache ENABLED, RAID Read Cache DISABLED, Write Cache Buffer Flush DISABLED.

    (Look at the delicious 21220MB/s read 1532MB/s write…. Yummo~~~)

    Q: Do I need to buy some sort of activation hardware or license to enable NVMe RAID on the AMD Threadripper platform?
    A: No. You only need to follow the steps 1-5 outlined in this blog.

    Q: Is your NVMe RAID solution bootable?
    A: Yes. Create the RAID array with the RAID management menu(s) in your BIOS, then proceed with Windows installation. Please ensure that your system is in pure UEFI mode by installing Windows with Compatibility Support Module (CSM) disabled in your BIOS. You will also need the NVMe RAID driver on a flash drive, as the Windows installer will ask for it before your array can be detected.

    Q: What RAID levels are supported?
    A: RAID0 (striping), RAID1 (mirroring), RAID10 (striping with mirroring). Please note that RAID10 requires four or six NVMe devices by design.

    Q: How many simultaneous SSDs can I run?
    A: The AMD Ryzen™ Threadripper™ platform supports up to seven simultaneous PCIe® devices without adapters. Provided you have one GPU in the system, this sets a practical limit for most users of six NVMe SSDs.

    Q: How are the NVMe SSDs electrically connected to the system?
    A: NVMe SSDs are connected to the system over the PCI Express® bus. These PCI Express lanes come directly from the AMD Ryzen™ Threadripper™ processor, rather than being routed through a relatively narrow link from the chipset.

    Q: What AMD chipsets are compatible with NVMe RAID?
    A: The AMD X399 chipset is compatible with our free NVMe RAID solution.

    Q: Is hotswap supported in RAID1 and RAID10 arrays?
    A: Yes.

    Q: When will the required BIOS update be available for my ASUS AMD X399-based motherboard?
    A: Coming soon. You should expect to see some starting to show up from late this week.

    Q: Do all AMD Ryzen™ Threadripper™ CPUs and motherboards qualify for NVMe RAID support?
    A: Yes.

    Q: What operating systems are supported?
    A: Windows® 10 x64 (build 1703) is supported at this time.

    Q: Can I use any NVMe SSD with this update?
    A: Yes.

    Q: If I already have a RAID array of SATA disks, can I just upgrade my driver and BIOS to add NVMe RAID support?
    A: In-place upgrades of the RAID driver are not supported at this time. Please back up your data and break down your array prior to installing an NVMe RAID-ready BIOS or driver. AMD recommends that users start fresh with a new NVMe RAID array and a new install of Windows. To this effect, our knowledgebase article offers standalone drivers suitable for placing onto a flash drive for the Windows installer.

    My NMVe drives do not show up in the Advanced\RAIDXpert Configuration, only my SATA drives. Do we need to wait for a BIOS update?

    Hi RaskTreve,

    Yes, BIOS update will be required.
    At the moment we are still awaiting for update from AMD for official release of this NVMe RAID function. Please stay tuned for updates.
