One of the most interesting features about AMD’s X399 platform is the fact that there are 64 PCIe lanes. While 4 lanes are dedicated to the chipset, the other 60 lanes are for PCIe devices such as graphics cards, a sound card and apparently NVMe SSDs. When AMD Ryzen Threadripper launched, the NVMe RAID support was missing. Although for some this feature might be important, we didn't think it was a big loss since a NVMe RAID setup is quite uncommon.

According to AMD, it has been reported that NVMe RAID is now supported on AMD’s X399 platform. In order to enable this feature, you have to install a software update which will be available by September 25th. The software update comes in the form of both a driver update and a motherboard BIOS update. After the update, you should be able to create RAID 0, RAID 1 and RAID 10 arrays with up to 10 NVMe SSDs.

Although this feature might be not interesting for many of you, it's still a big step for AMD. Intel is offering a similar solution on the X299 platform, however the Virtual RAID On CPU (VROC) system needs to be enabled with a small dongle key that is sold by Intel. Out of the box, if you have Intel drives, an ASUS Hyper M.2 card and a Skylake-X CPU, you can build RAID 0 arrays. If you want to enable RAID 1, RAID 5 and other RAID schemes, you have to buy this Intel key to enable it.
