2x Samsung PM9A1 MZVL21T0HCLR (RAID 0)

2x PM9A1 MZVL21T0HCLR (RAID 0)

Two Samsung OEM Client SSD PM9A1 1TB in RAID 0 combination offer 2 TB of storage and a higher performance than a single drive but at the cost of a higher power consumption and a higher risk  of data loss (data lost if one drive has a failure). Each drive uses the Samsung Elpis (S4LV003) Controller with 8 channels and 512 MB LPDDR4. The memory modules are from Samsung (3D-NAND TLC 136 layers). The 1TB version is specified at 7000 MB/s and 5100 MB/s write (SLC cached). The power consumption is specified at 0.005 W (sleep) and 0.035W (idle) for each drive.
