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.

Questions about this item

What does the 550 MB/s sequential read speed mean for a server workload?

The 550 MB/s figure is the maximum sustained read rate over the SATA interface. Real-world throughput will be lower due to controller overhead, queue depth and the specific read-intensive application pattern.

How does the SATA 600 interface limit this drive's performance?

The SATA 600 (6 Gb/s) link caps theoretical bandwidth at 600 MB/s, so the drive's 550 MB/s read and 510 MB/s write ratings already sit near the interface ceiling.

Will the 2.5-inch 7 mm form factor fit my server's drive bay?

The drive measures 2.5 inches wide and 0.3 inches (7 mm) high, matching the standard 2.5-inch 7 mm bay used in most enterprise servers and storage arrays.
