Enterprise SATA SSD for 240GB server storage

The Solidigm D3-S4520 is a 2.5 inch internal drive built for data-centre and server workloads. It connects through a SATA III interface and uses 144L TLC 3D NAND to deliver 240GB of capacity. The drive is rated for 2,000,000 hours MTBF and operates between 0°C and 70°C.

Suited for read-heavy server arrays.

This SSD fits servers that need reliable sequential reads of 470 MB/s and random 4KB reads of 44,000 IOPS. Builders who need higher sustained write throughput or larger endurance than 1024 TBW should look at drives specified for those workloads.

1024 TBW endurance rating defines the write life

The drive warrants 1024 terabytes written over its lifetime, a figure that directly determines how long it can serve in mixed read-write server environments before wear-out.

Questions about this item

What does the 470 MB/s read speed mean for a server workload?

The 470 MB/s maximum read transfer rate is the peak sequential throughput the D3-S4520 can sustain over the SATA 6Gb/s link when the controller and queue depth allow it.

How does the SATA 6Gb/s interface limit this drive?

The SATA 6Gb/s interface caps practical throughput at the drive's rated 470 MB/s read and 233 MB/s write, well below the bus ceiling.

Will the 2.5 inch form factor fit a standard server drive bay?

Yes, the 2.5 inch form factor with a 0.3 inch height matches the common 7 mm server drive bay and caddy dimensions.
