Capacity and form factor

The Intel DC S3520 is a 1.6TB 2.5-inch enterprise SSD built with MLC memory and a SATA III interface. It targets servers and storage arrays that need consistent read performance and power-efficient operation.

Upgrade from DC S3510

Compared with the DC S3510 series, this drive delivers 15% lower idle power, 30% lower active write power and 35% better performance per watt. The jump is worth it when density and efficiency matter more than peak throughput.

SATA interface limits

The SATA III link caps sequential reads at 450 MBps and writes at 380 MBps, while random performance reaches 67,500 read IOPS and 17,000 write IOPS. Latency sits at 40 µs read and 42 µs write, so workloads needing higher bandwidth or lower latency will require a different interface.

Questions about this item

Does the 2.5 inch 7 mm SSDSC2BB016T701 fit in a standard 2.5 inch drive bay?

The SSDSC2BB016T701 is a 2.5 inch form factor drive with a 7 mm height, so it fits standard 2.5 inch bays that accept 7 mm drives.

What is the correct way to install the Intel DC S3520 SATA III SSD and what step is often missed?

Connect the SATA data cable and the SATA power cable securely; the step often missed is ensuring the SATA data connector clicks fully into the port on both the drive and the motherboard or controller.

When will the 1.6TB MLC drive with 1.0 DWPD rating need replacement under typical write workloads?

At 1.0 DWPD the 1.6TB drive is warrantied for 1.6TB of writes per day; with a 2,000,000 hour MTBF, replacement timing depends on your actual daily write volume.
