03GX015 Lenovo ThinkSystem 3.5in Nytro 3732 800GB Performance SAS 12Gb Hot Swap SSD

Spare number 03GX015 matches option 4XB7A70010, feature code BG02: the 800 GB, 3.5-inch Nytro 3732 Performance SAS SSD with a hot-swap tray. Seagate 3D eTLC flash sits behind a 12 Gbps SAS interface. AES 256-bit encryption is supported across the series.

Endurance is 10 DWPD for 5 years, which totals 14,600 TB written. At 800 GB the drive reads 180,000 IOPS and writes 200,000 IOPS using 4 KB blocks, while 128 KB blocks move at 1100 MBps reading and 1000 MBps writing. Random latency comes to 115 µs for a read and 25 µs for a write.

At 800 GB, a read draws 9.3 W and a write 7.7 W on average. MTBF is 2,500,000 hours and the error rate is under 1 in 10^17 bits read. Non-operating shock is 1,000 G at 0.5 ms and non-operating vibration is 11.08 GRMS from 20 to 2000 Hz. Operating temperature runs from 0 to 70°C.

Data-path protection includes extended ECC, XOR parity against flash die failure and parity-checked internal paths with no external write cache; power loss data management needs no supercapacitor. Up to 32 initiators and a command queue of 128 are supported, with S.M.A.R.T. reporting. The drive is 15 mm high and weighs 136 g without its tray. Same 3.5-inch range: 4XB7A70011 (400GB), 4XB7A70009 (1.6TB), 4XB7A70008 (3.2TB).
