Enterprise SATA SSD for data centres

The Solidigm D3-S4520 is a 240GB 2.5" SATA III drive built with 144L TLC 3D NAND. It targets server and storage arrays that need consistent read performance and a 2.5 DWPD endurance rating. The drive delivers up to 470 MBps sequential read and 44,000 random read IOPS with a 2,000,000 hour MTBF.

Upgrade from lower-endurance SATA drives

This model replaces consumer or entry-level SATA SSDs when workloads demand 1.0 PBW write endurance and steady 233 MBps sequential write speeds. The jump is worth it for mixed read-write applications that exceed 15,500 random write IOPS or require 102µs read latency and 61µs write latency under sustained load.

Fits 2.5" hot-swap bays and standard SATA backplanes

The drive operates from 0°C to 70°C while drawing 1W idle and 2.3W active, simplifying thermal planning in dense chassis. It withstands 1,000 G shock and 2.17 GRMS operating vibration, freeing administrators from extra ruggedisation hardware in standard rack environments.

Questions about this item

Does the 2.5" form factor fit a standard 7 mm drive bay?

The drive uses a 2.5 inch SATA form factor; most server trays accept the standard 7 mm height but verify your chassis specifications before ordering.

What is the correct way to connect the SATA power and data cables?

Attach both the SATA data cable and the 15 pin SATA power connector; a common mistake is leaving the power cable loose which prevents the drive from spinning up.

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

The drive is rated for up to 2.5 DWPD or 1.0 PBW; monitor SMART wear indicators and replace once the media wearout counter approaches the rated limit.
