4XB7A80499 is the ThinkSystem E1.S 5.9mm 7450 PRO 7.68TB Read Intensive NVMe PCIe 4.0 x4 HS SSD, Lenovo feature code BPKW, with supplier model MTFDKBZ7T6TFR-1BC15ABYY. It belongs to the ThinkSystem 7450 PRO family, which is based on the Micron 7450 PRO and uses Micron 176-layer 3D TLC NAND with a direct PCIe 4.0 x4 connection to each drive. This one is the E1.S 5.9 mm hot-swap form factor.
At 7.68 TB the drive reaches 1,000,000 IOPS on 4 KB random reads and 215,000 IOPS on 4 KB random writes. Sequential reads run at 6800 MBps and sequential writes at 4000 MBps on 128 KB blocks, and random latency is 80 microseconds for reads and 15 microseconds for writes. Endurance is 1.0 DWPD over five years, which is 14,000 TB written. MTBF is 2,000,000 hours, data reliability is better than 1 error in 10^17 bits read, and typical power is 12.0 W for both reading and writing.
SED encryption is standard and complies with TCG Opal 2.01, with a secure execution environment, asymmetric roots of trust, secure boot and key-based firmware update. Power-loss protection, Adaptive Thermal Monitoring that adjusts power to stay within thermal limits, end-to-end data protection and S.M.A.R.T. reporting complete the feature set.
