Solidigm D3-S4520 1.92TB 2.5" SATA enterprise SSD (SSDSC2KB019TZ01)

Capacity and interface

This Solidigm D3-S4520 is a 1.92TB enterprise SSD built in a 2.5-inch 7mm form factor with a SATA 6Gb/s interface. It uses 144L TLC 3D NAND to deliver sequential reads up to 550 MB/s and writes up to 510 MB/s, with random 4KB performance of 91000 IOPS read and 38000 IOPS write. A 256-bit encryption standard and a 2,000,000-hour MTBF support data-centre reliability.

Read-intensive workloads and SATA infrastructure

The drive suits operators who need high-capacity, power-efficient storage for read-heavy server workloads while retaining existing SATA backplanes and cabling. Buyers who require higher random write IOPS or greater write endurance for mixed or write-intensive applications should evaluate alternative drive types. The 0°C to 70°C operating range and 1,000 G shock resistance fit standard rack environments.

Endurance class for the workload

The D3-S4520 is positioned as a read-optimised enterprise SSD, so its write endurance rating is lower than mixed-use or write-intensive models. Confirm that your application’s daily write volume aligns with a read-intensive endurance class before deployment. The five-year limited warranty covers the drive under those intended conditions.
