2x Samsung PM981a MZVLB1T0HBLR (RAID 0) 2x MZVLB1T0HBLR (RAID 0)

Two Samsung SSD PM981a 1TB nVME SSDs (MZVLB1T0HBLR-00000) in RAID 0 adds some performance to the already fast PM981a but also adds a higher risk of data loss. Each single SSD is a high end M.2 2280 SSD based on the Samsung Phoenix Controller (S4LR020) with 8 channels. The power consumption is specified with 2x 0.03 W in idle and 2x 5.6 W under load. The PM981a uses Samsung 3D-NAND TLC with 96 layers (V-NAND v5) and uses NVMe 1.3.
