41Y8331 Lenovo S3700 200GB SATA 2.5in MLC Enterprise SSD

41Y8331 is Lenovo's S3700 200GB SATA 2.5" MLC HS Enterprise SSD (feature code A4FL): a 200GB S3700 Enterprise drive in the 2.5-inch size and ships mounted on a 2.5-inch hot-swap tray.

Intel 25 nm MLC flash with High Endurance Technology sits behind a 6 Gbps SATA interface in this S3700 drive. Lenovo lists AES-256 encryption, end-to-end data path protection, thermal throttling and power loss data protection, plus 2,000,000 hours MTBF and 50/65 microsecond read/write latency.

For the 200GB model Lenovo gives 3.65 PB total bytes written for five years, 75,000/32,000 read/write IOPS on 4 KB transfers and 500 MBps/365 MBps sequential read/write on 128 KB transfers.

Lenovo sizes the S3700 line for write-heavy work: the whole drive can be rewritten up to ten times a day for five years. That is the main difference from Enterprise Value SSDs, which have a lower cost per IOPS but far less endurance.

Lenovo's compatibility tables list it for the x3100 M4 and M5, x3250 M4, x3300 M4, x3500 M4, x3530 M4, x3550 M4, x3650 M4 and x3650 M4 HD, x3690 X5, x3750 M4 and x3850 X5/x3950 X5, plus BladeCenter HS22, HS23 and HS23E and Flex System x220, x240 and x440. Lenovo's Configuration and Options Guide of 17 January 2017 also lists it for the x3100 M5 (5457) and x3750 M4 (8753), marked with an asterisk as withdrawn.

Fit check: verify the 2.5-inch hot-swap bay, the server model and the 41Y8331 label. Same-family pages: 41Y8336 and 00AJ156.
