Can I use NVMe and SSD for RAID?

SSD NVMe are installed on PCIe cards and not controlled by Storage controller, that is why SSD NVMe is not supported on Hardware RAID. These drives are desgined for very high peromance. You can only create a Hardware RAID if Storage devices are connected directly to the Storage Controller.

Can you RAID NVMe and SSD?

RAID functions on NVMe SSDs much like previous storage devices. Independent hardware vendors also support hardware acceleration based on cards. Usually, NVMe leverages the SSD technology using the “Submission and Completion Queue” mechanism. RAID is the best solution.

Does NVMe support hardware RAID?

RAID works on NVMe SSDs just like it did on previous storage devices. Linux mdadm supports NVMe RAID and has enhancements to improve reliability, performance, and scalability. There are independent hardware vendors that support NVMe based RAID cards for hardware acceleration as well.

Can you mix SSD and HDD in RAID?

Even though it’s possible to set up a RAID with SSD and HDD, the outcome will be an array performing only as fast as the slowest drive. Mixing RAID with SSD and HDD will lower the bar if you consider any RAID configuration, whether striping, mirroring, or parity, simply because an HDD can do only so much.
