41Y8336 Lenovo S3700 400GB SATA 2.5in MLC Enterprise SSD

The S3700 400GB SATA 2.5" MLC HS Enterprise SSD carries Lenovo option number 41Y8336 and feature code A4FN. Capacity is 400GB, form factor 2.5-inch and ships mounted on a 2.5-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 41Y8336 at 7.3 PB written over a five-year life, 75,000 read and 36,000 write IOPS, 500 MBps sequential read and 460 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.
