Overview

Lenovo ThinkSystem 3.84TB SATA 6G SFF S4520 Read Intensive Hot-Swap SSD, part number 4XB7A17104, brings 3.84TB into a standard 2.5in bay. For read-heavy data sets, that means fewer drives per terabyte and more free slots for growth.

The drive uses Intel 144-layer 3D NAND TLC and a SATA link at 6 Gbps. Endurance is 2.1 DWPD, or 15300 TB written. Sequential speeds are 550 MB/s read and 510 MB/s write; random figures are 92000 IOPS read and 31000 IOPS write, with latency of 104 µs for reads and 57 µs for writes. Power is 3.5 W, MTBF is 2000000 hours, and there is no encryption. Lenovo files it under feature code BK77.

The compatibility list is long, reaching from the SR630 and SR650 through V2 servers such as the SR650 V2 to V3 models like the SR630 V3, SR650 V3, SE455 V3 and SD535 V3. The FAQ gives the full list.

New, Refurbished and Used offers exist for this part number. New and Refurbished units have 1 year or 3 years of warranty. Used units have 90 days. Add your quantity to a request and we will price each condition.
