Within the 3.5-inch Intel S4510 Read Intensive hot-swap range, 480 GB is option 4XB7A13626 (B49E), and Lenovo spare 01PE331 corresponds to it. Intel 64-layer 3D NAND TLC provides the storage and a 6 Gbps SATA interface carries the data. The drive is not self-encrypting at this capacity, although AES 256-bit encryption is supported.
Write endurance is 1.4 DWPD, and five years add up to 1.2 PB. Small-block operation (4 KB) tops out near 95,000 reads and 18,000 writes per second. 128 KB sequential speeds are 560 MBps for reads and 490 MBps for writes. Latency numbers are 36 µs and 37 µs for sequential read and write, and 103 µs and 73 µs for random read and write.
Operating shock tolerance is 1,000 G at 0.5 ms, operating vibration is 2.17 G RMS (5-700 Hz) and non-operating vibration is 3.13 G RMS (5-800 Hz). MTBF reaches 2,000,000 hours, uncorrectable errors stay below 1 in 10^17 bits read, and typical active write power is 3.0 W. S.M.A.R.T., thermal throttling and enhanced power loss data protection complete the feature set.
Neighbours in the 3.5-inch hot-swap S4510 numbering are 4XB7A13625 (B49D, 240GB) and 4XB7A13627 (B49F, 960GB), followed by 1.92TB, 3.84TB and 7.68TB drives under 4XB7A13628, 4XB7A13629 and 4XB7A13630.
