4XB7A10240 is the ThinkSystem 2.5" 5200 1.92TB Mainstream SATA 6Gb Hot Swap SSD, Lenovo feature code B48B. It is a Lenovo version of the Micron 5200 MAX drive, using Micron 64-layer triple-level cell 3D NAND behind a 6 Gbps SATA interface, and it is aimed at mixed read and write workloads. The 3.5-inch hot-swap build of the same capacity is 4XB7A10245 (feature B48G).
The 1.92 TB size has an endurance of 5.0 DWPD over five years, which is 17,520 TB written. It reaches 95,000 IOPS on 4 KB random reads and 70,000 IOPS on 4 KB random writes, with sequential speeds of 540 MBps read and 520 MBps write on 128 KB blocks. Read latency is 200 microseconds and write latency is 300 microseconds. MTBF is 3,000,000 hours, data reliability is better than 1 error in 10^17 bits read, and typical power is 3.0 W reading and 3.6 W writing.
The drive supports AES 256-bit encryption and S.M.A.R.T. monitoring and has no moving parts. Without its tray the body measures 7 mm x 70 mm x 100 mm and weighs 70 g, and it withstands 1,500 G of non-operating shock at 0.5 ms and 3.13 G RMS of non-operating vibration across 5 to 800 Hz.
