4XB7A93140 (feature code C286) is the ThinkSystem M.2 VA 480GB Read Intensive NVMe NHS SSD. VA means Vendor Agnostic, and NHS means non-hot-swap. The drive is an M.2 2280 module with SED encryption, built for read-intensive and general-purpose data center workloads.
At 480GB the drive reaches 54,000 random read IOPS and 27,000 random write IOPS with 4 KB blocks, plus 2,900 MBps sequential read and 900 MBps sequential write with 128 KB blocks. Endurance is 0.1 drive writes per day over five years, or 100 TB total bytes written, with an MTBF of 2,000,000 hours and a data reliability figure of fewer than 1 uncorrectable error in 10^15 bits read.
Adapter fit matters for this part number. Lenovo supports it only on the internal ThinkSystem M.2 RAID B550i-2i and M.2 B350i-2i adapters. It is not supported on the B545 and B340 adapters or on the adapters that came before them. The hot-swap twin, 4XB7B14665, carries the same drive data and is the one for the B550p and B550d hot-swap M.2 adapters.
The same family continues at 960GB as 4XB7A93141 and at 1.92TB as 4XB7A93142, each with its own capacity-specific figures. For a SATA M.2 drive from the Vendor Agnostic line, see the ThinkSystem M.2 VA 480GB Read Intensive SATA NHS SSD, 4XB7B07588, or browse more Lenovo SSDs.
