Enterprise read-intensive SSD

The Solidigm D3-S4620 is a 1.92TB 2.5" SATA drive built for server workloads that read far more than they write. Its 144L TLC 3D NAND and 256-bit encryption suit data centres needing steady throughput and hardware-level data protection.

Endurance and encryption

A 14336 TBW rating gives long service life under constant read traffic, while the 256-bit encryption standard secures data at rest without host software overhead. The SATA 600 interface keeps integration simple on existing backplanes and RAID controllers.

Read-heavy headroom

Sequential reads reach 550 MBps and random 4KB reads hit 91000 IOPS, so boot volumes, content repositories and cached databases run smoothly. Sequential writes top out at 510 MBps and random writes at 53000 IOPS, so sustained heavy ingest or log-heavy workloads will saturate the drive.

Questions about this item

How long will the 14336 TB endurance rating last before the drive needs replacement?

The 14336 TB total bytes written rating means the SSD can absorb that much host data over its service life; in a typical read-heavy server workload it translates to several years before wear-out requires a swap.

Which limit appears first during sustained heavy writes — the SATA 600 interface ceiling or the NAND write speed?

Sequential writes top out at 510 MB/s, which is below the SATA 600 maximum, so the NAND write path is the bottleneck you hit first under continuous load.

How much heat does the 2.5 inch drive generate when it runs all day in a server chassis?

The drive is rated for 0 °C to 70 °C operating temperature and has no moving parts, so it adds minimal heat; standard server airflow across the 2.5 inch bay keeps it well within limits.
