The 1.92 TB drive in the 3.5-inch Mainstream 5100 line, option 7SD7A05757 with feature code B114, is the one that spare 01GT756 stands for. It carries the name ThinkSystem 3.5-inch 5100 1.92TB Mainstream SATA 6Gb hot-swap SSD and is the Lenovo version of the Micron 5100 PRO.
Endurance is quoted as 8,800 TB of total bytes written, which is 2.5 drive writes per day over five years; written another way, a three-year life would allow 4.2 drive writes per day. Four-kilobyte random reads reach 93,000 IOPS and writes reach 37,000 IOPS. Streaming 128 KB blocks, the drive reads at 540 MBps and writes at 520 MBps.
Triple-level cell 3D NAND sits behind the 6 Gbps SATA interface. Sequential latency is 500 µs each way, MTBF is 2,000,000 hours, and the read error rate is below 1 in 10^17 bits. Typical power is 5.5 W. The feature set adds S.M.A.R.T. support and AES 256-bit encryption support.
Other capacities carry these Mainstream 3.5-inch hot-swap option numbers: 7SD7A05760 for 240GB, 7SD7A05759 for 480GB, 7SD7A05758 for 960GB and 7SD7A05756 for 3.84TB. Feature codes follow the capacity order, from B111 for 240GB up to B115 for 3.84TB.
