Spare 01GT749 is the 480GB Mainstream drive of the 5100 SATA range in 2.5-inch hot-swap form, and the 480 GB size is the Lenovo version of the Micron 5100 MAX, whereas the other Mainstream capacities are 5100 PRO versions. Lenovo assigns it option 7SD7A05764 with feature code B10X.
Endurance at this capacity is 5.0 drive writes per day, stated as 4400 TB of total bytes written. Small-block ratings are 93,000 read IOPS and 74,000 write IOPS; sequential reads run at 540 MBps and sequential writes at 460 MBps.
Both sequential directions show 500 µs latency. The NAND is triple-level cell 3D, the host link runs at 6 Gbps over SATA, S.M.A.R.T. reporting and AES 256-bit encryption are supported, and MTBF is rated of 2,000,000 hours. Typical power is 4.5 W, and the unrecoverable read error rate is under 1 in 10^17 bits.
Other 2.5-inch hot-swap Mainstream options: 7SD7A05765 (240GB, B10W), 7SD7A05763 (960GB, B10Y), 7SD7A05762 (1.92TB, B10Z) and 7SD7A05761 (3.84TB, B110). Each of these relatives is a 2.5-inch hot-swap drive too, with its own capacity, endurance figure and write rate.
