240 GB SATA enterprise SSD

The Solidigm D3-S4520 is a 240 GB M.2 2280 drive built for data-centre workloads. It uses 144L TLC 3D NAND and a SATA III interface to deliver consistent performance in server and storage arrays. Rated endurance reaches 2.4 DWPD and 1.0 PBW with a 2,000,000-hour MTBF.

Read-intensive server deployments

This drive suits read-heavy applications such as boot volumes, logging tiers and content delivery caches where sequential reads up to 400 MBps and random reads up to 42,000 IOPS matter. Write-intensive databases or high-transaction OLTP systems needing higher sustained write throughput should look at drives with greater write endurance.

SATA III interface

The single specification that decides fit is the SATA III interface; the drive only works in slots and controllers that support SATA signalling. An M.2 socket wired for PCIe only will not operate this SSD.

Questions about this item

Does the M.2 2280 form factor fit a standard 80 mm slot?

Yes, the drive follows the M.2 2280 standard which is 80 mm long and mounts in a standard M.2 socket.

What is the correct way to secure the drive and avoid damaging the SATA connector?

Insert the drive at an angle into the M.2 slot, press it flat and fasten the single mounting screw; do not force the connector or overtighten the screw.

When should I plan to replace the drive based on its rated endurance?

The drive is rated for 1.0 PBW or 2.4 DWPD; monitor SMART wear indicators and replace before the media reaches its rated write limit.
