03GX016 Lenovo ThinkSystem 3.5in Nytro 3732 400GB Performance SAS 12Gb Hot Swap SSD

The 400 GB Nytro 3732 in a 3.5-inch hot-swap tray carries option number 4XB7A70011 and feature code BG03, and Lenovo spare 03GX016 corresponds to it. The SAS interface runs at 12 Gbps and the flash is Seagate 3D eTLC.

Rated life is 10 drive writes per day across five years, or 7,300 TB written in total. Four-kilobyte operations reach 170,000 reads and 200,000 writes per second. Sequential transfer with 128 KB blocks is 1100 MBps for reads and 950 MBps for writes, and random latency is 115 µs for reads against 25 µs for writes.

Average consumption is 8.9 W during reads and 7.9 W during writes. MTBF reads 2,500,000 hours, with fewer than 1 in 10^17 bits read returned in error. The non-operating limits are 1,000 G shock for 0.5 ms and 11.08 GRMS vibration between 20 and 2000 Hz; operating temperature spans 0 to 70°C, and humidity from 5 to 95 percent without condensation.

Supported functions are S.M.A.R.T., AES 256-bit encryption, 32 initiators with tagged command queuing to 128 commands, and compliance with SAS-3, SPL-3, SBC-4, SPC-5 and SAM-6. Flash die failure is covered by XOR parity, and power loss data is managed without a supercapacitor. Drives of 800GB, 1.6TB and 3.2TB use 4XB7A70010, 4XB7A70009 and 4XB7A70008 in the same 3.5-inch format.
