Intel DC S3520 240GB SATA SSD

The Intel DC S3520 240GB SATA SSD is an enterprise-grade drive built for read-intensive data centre workloads. It uses MLC 3D NAND and a 2.5-inch form factor with a SATA III interface. The drive targets boot, web serving, and light database tasks where consistent latency matters.

Check SATA power and bay compatibility

Verify that your server or array has a free 2.5-inch drive bay and a SATA power connector. The drive draws 0.5W idle and 2.8W active, so the backplane must supply enough current. Confirm the controller supports SATA III speeds and that firmware is current for enterprise drives.

Efficiency gains over the DC S3510 series

Compared to the DC S3510 series, this model uses 15% less idle power and 30% less active write power. The efficiency improvement reaches +35% performance per watt. Endurance is rated at 1.0 DWPD with a 2,000,000-hour MTBF, and the drive operates from 0°C to +70°C.

Highlights

  • Enterprise-grade reliability with 2,000,000 hours MTBF

Questions about this item

Does the Intel DC S3520 240GB include a mounting bracket or cables, or must they be purchased separately?

The drive ships as a bare 2.5" SATA unit; brackets, screws and data cables are not included and must be sourced separately.

Which capacity of the S3520 series suits a read-intensive boot or web-server workload?

The 240GB model offers 1.0 DWPD endurance and 65,000 random read IOPS, matching typical boot and web-tier requirements.

What does the 320 MBps sequential read figure mean when the drive is installed in a server?

In a SATA 6 Gbps backplane the drive can sustain up to 320 MBps sequential reads, with 40 µs read latency and 2.8 W active power draw.
