Intel DC S3520 480GB SATA enterprise SSD

The Intel DC S3520 is a 480GB 2.5-inch SATA solid-state drive built for server and storage arrays. It uses MLC flash and delivers sequential reads up to 450 MBps and writes up to 380 MBps with 65,500 random read IOPS and 16,000 random write IOPS. The drive is rated at 1.0 DWPD endurance and a 2,000,000-hour MTBF for mixed read-write workloads.

Compatibility checklist for your server

Verify that your system provides a 2.5-inch drive bay with a SATA III connection and can supply 3.2 W active power and 0.5 W idle power. The 7 mm z-height fits standard bays but confirm clearance if using a slim chassis or hot-swap tray. Operating temperature range is 0 °C to 70 °C, so ensure adequate airflow in the enclosure.

Efficiency gains over the previous series

Compared with the DC S3510 series this model reduces idle power by 15 percent and active write power by 30 percent while raising performance per watt by 35 percent. Read latency is 42 µs and write latency is 40 µs. The drive withstands 1000 G shock and 2.17 GRMS operating vibration for reliable operation in dense racks.
