1 Overview
This document describes the specifications and capabilities of the Intel® SSD DC S3520 Series.
The Intel® SSD DC S3520 Series delivers great performance and Quality of Service combined with high
reliability for Serial Advanced Technology Attachment (SATA)-based computers in capacities of 150GB,
240GB, 480GB, 800GB, 960GB, 1.2TB and 1.6TB in a 2.5-inch form factor and 150GB, 240GB, 480GB,
760GB, and 960GB in the M.2 form factor
By combining Intel’s 3D MLC NAND Flash Memory technology with SATA 6 GB/s interface support, the
Intel SSD DC S3520 Series delivers Sequential Read speeds of up to 450 MB/s and Sequential Write
speeds of up to 400 MB/s. The Intel SSD DC S3520 Series also delivers Random 4k Read speeds of up to
