Enterprise SATA SSD with 1.92TB capacity

The Solidigm D3-S4520 is a 2.5 inch enterprise SSD built for read-intensive server workloads. It uses 144L TLC 3D NAND and connects through a SATA III interface. The drive suits data centres that need reliable capacity for boot, logging or content repositories.

Fits standard 2.5 inch bays and SATA backplanes

The drive drops into any 2.5 inch hot-swap bay or internal cage wired for SATA III. Its 1.1W idle and 3.1W active draw keep power budgets low, freeing headroom for additional drives or other components. No special cabling or controller features are required beyond the standard SATA link.

Steady performance under sustained write load

Rated at 2.5 DWPD and 8.8 PBW, the drive maintains consistent throughput during long write sequences. Sequential speeds reach 550 MBps read and 510 MBps write, while random performance holds at 91,000 read IOPS and 38,000 write IOPS. Latency stays at 104µs read and 54µs write, and MTBF of 2,000,000 hours supports continuous operation.

Questions about this item

How long will the 2.5 DWPD endurance rating last under continuous mixed workloads?

The drive is rated for up to 2.5 drive writes per day or 8.8 PBW total bytes written, meaning a full 1.92TB write each day for five years before reaching the endurance limit.

What are the steady-state power draw and operating temperature when the SSD runs 24/7?

Active power consumption is 3.1W and the operating temperature range is 0°C to 70°C, so sustained use stays within those thermal and power bounds.

Which host interface and connector must the server already provide for this 2.5" SATA III drive?

The system needs a standard 2.5-inch SATA 6Gb/s port with the combined data and power connector to install and operate the SSD.
