A 3.5-inch large-form-factor hot-swap tray holds the 480 GB S4620 Mixed Use drive that Lenovo spare 02JG594 stands for. The option number is 4XB7A17137 and the feature code BA4W. Flash is 144-layer Intel 3D NAND TLC behind a 6 Gbps SATA connection, and the model has no SED encryption.
Protection features include end-to-end data path protection, enhanced power loss data protection, S.M.A.R.T., AES 256-bit encryption and thermal throttling to extend drive life. The drive has no moving parts. MTBF stands at 2,000,000 hours and the unrecoverable read error rate is under 1 in 10^17 bits.
Endurance reads 4.7 DWPD across five years, which is 4.2 PB of data written. Small 4 KB blocks reach 85,000 read IOPS and 48,000 write IOPS; 128 KB sequential streams reach 550 MBps and 500 MBps respectively. Sequential latency is 36 µs both ways, random read latency 103 µs, random write latency 43 µs. Typical write power is 3.0 W, with operating shock at 1,000 G for 0.5 ms.
Same-tray siblings in the S4620 3.5-inch hot-swap run: 960GB as 4XB7A17138 (BA4X), 1.92TB as 4XB7A17139 (BA4Y), 3.84TB as 4XB7A17140 (BK7P). The 480GB simple-swap variant is a separate option, 4XB7A17134 (BK7M).
