Spare 03KH560 corresponds to Lenovo option 4XB7A83218, feature code BR0W, a 400 GB Nytro 3750 Write Intensive SSD in the 3.5-inch hot-swap form. Its Seagate model is XS400ME70055. Seagate 3D eTLC flash is used with a 12 Gbps SAS connection, and every drive in the Nytro 3750 series encrypts with TCG Enterprise.
Total bytes written is rated at 7,300 TB, which is 10 DWPD over 5 years. In 4 KB tests the drive reaches 148,000 reads and 161,000 writes per second. Sequential transfers of 128 KB blocks proceed at 1105 MBps reading and 1096 MBps writing, and random access latency is 115 µs for a read and 25 µs for a write.
Typical electrical draw is 7.7 W reading and 5.6 W writing. Mean time between failures is 2,500,000 hours, and fewer than 1 in 10^17 bits read come back in error. The drive withstands 1,000 G non-operating shock for 0.5 ms and 11.08 GRMS non-operating vibration from 20 to 2000 Hz, and humidity from 5 to 95 percent non-condensing.
Other functions include 32 initiators with a 128-command queue, S.M.A.R.T., AES 256-bit encryption, Sanitize Cryptographic Erase and SafeStore support on ThinkSystem RAID adapters. The command sets followed are SAS-3, SPL-3, SBC-4, SPC-5 and SAM-6. Larger 3.5-inch Nytro 3750 options are 4XB7A83219 (800GB), 4XB7A83220 (1.6TB) and 4XB7A83221 (3.2TB).
