Lenovo option 4XB7A17140 (feature code BK7P) carries spare number 02JG597. It is the 3.84 TB member of the 3.5-inch S4620 Mixed Use hot-swap range: Intel 144-layer 3D NAND TLC flash, a 6 Gbps SATA link and a large-form-factor tray.
Five full drive writes per day are rated over five years at this capacity, totalling 35.1 PB written. Expected reliability is 2,000,000 hours MTBF with fewer than 1 in 10^17 bits read returned in error. SED encryption is not part of this model, while AES 256-bit encryption, S.M.A.R.T. and end-to-end data path protection are.
Throughput with 4 KB blocks is 91,000 read IOPS and 60,000 write IOPS, and 128 KB sequential speeds are 550 MBps read and 510 MBps write. Sequential latencies are 36 µs and 38 µs; random access takes 104 µs for reads and 45 µs for writes. Average active write power is 3.9 W. Operating limits include 1,000 G shock at 0.5 ms and 2.17 G RMS vibration from 5 to 700 Hz, and temperature may run from 0 to 70°C.
Other 3.5-inch hot-swap S4620 numbers: 4XB7A17137 for 480GB (BA4W), 4XB7A17138 for 960GB (BA4X) and 4XB7A17139 for 1.92TB (BA4Y), all in the Mixed Use class over 6 Gbps SATA.
