Lenovo lists 4XB7A90102 (feature code BXMH) as the ThinkSystem M.2 PM9A3 960GB Read Intensive NVMe PCIe 4.0 x4 non-hot-swap SSD. Its vendor part number is MZ1L2960HCJR-00A07. The M.2 size is 22110, and the drive supports TCG Opal self-encryption.
At 960GB Lenovo rates endurance at 1 drive write per day over 5 years, which is 1,752 TB written, with an MTBF of 2,000,000 hours and better than 1 unrecoverable bit error in 10^17 bits read.
Performance figures for this capacity are 550,000 random read IOPS and 60,000 random write IOPS at 4 KB, 5000 MBps sequential reads and 1400 MBps sequential writes at 128 KB. Random latency is 75 microseconds for reads and 30 microseconds for writes, and sequential latency is 20 microseconds both ways.
Typical power is 7.5 W reading and 6.5 W writing. Non-operating shock is rated at 1,500 G for 0.5 ms.
The M.2 range continues with 1.92TB (800,000 read and 85,000 write IOPS) and 3.84TB drives, which Lenovo rates at 5500 MBps sequential read.
Another NVMe SSD in the Lenovo SSD category is the Lenovo ThinkSystem 2.5-inch U.2 P5600 1.6TB mixed use NVMe PCIe 4.0 x4 SSD.
