00AJ480 Lenovo S3700 200GB SATA 3.5in MLC Enterprise SSD

Option 00AJ480, feature code A56G, is the S3700 200GB SATA 3.5" MLC HS Enterprise SSD. The drive is 200GB in the 3.5-inch format and ships on a 3.5-inch hot-swap tray.

The S3700 Enterprise drives use Intel 25 nm MLC NAND with High Endurance Technology (HET), which Lenovo describes as NAND silicon enhancements plus SSD NAND management that extend write endurance. Other listed features: 6 Gbps SATA, AES 256-bit encryption, full end-to-end data path protection, enhanced power loss data protection and 6 W typical power.

The specification table rates 00AJ480 at 3.65 PB written over a five-year life, 75,000 read and 32,000 write IOPS, 500 MBps sequential read and 365 MBps sequential write, with 6 W typical power.

The difference from Enterprise Value drives is endurance: Lenovo says an S3700 can be fully rewritten up to ten times per day across a five-year life, while an Enterprise Value SSD sustains about 0.4 full writes per day for the same life.

Servers that list this drive in the Lenovo guide: the x3550 M5 (5463), x3650 M5 (5462) and the x3630 M4 (7158). Lenovo's Configuration and Options Guide of 17 January 2017 also lists it for the x3500 M5 (5464), marked with an asterisk as withdrawn.

Fit check: the replacement must be a 3.5-inch hot-swap bay drive for a listed server; 00AJ480 carries feature code A56G. Family members with pages: 00AJ485 and 00AJ490.
