Data-centre SSD for read-intensive workloads

The Solidigm D7-P5520 is a 3.84TB enterprise drive built on 144L TLC 3D NAND with a U.2 15mm form factor. It connects through a PCI-Express 4.0 interface and delivers up to 6700 MBps sequential read and 3600 MBps sequential write speeds. The drive is rated for 7.0 PBW endurance and a 2,000,000-hour MTBF, and it includes FIPS security validation.

Suited to read-heavy server roles.

This SSD fits database servers, content-delivery nodes and analytics platforms that demand high random-read IOPS of 1000000 and moderate write IOPS of 200000. Its 15W active power and 5W idle draw suit dense 2.5-inch bays with standard cooling. Buyers who need substantially higher write endurance or a smaller M.2 footprint should evaluate other form factors.

PCIe 4.0 x4 lane width governs peak throughput

The drive requires a backplane or riser that can supply four PCIe 4.0 lanes to reach the stated 6700 MBps read ceiling. If the host slot negotiates at a lower generation or lane count, sequential and random performance will scale down accordingly. Confirm the platform PCIe topology before purchase.

Questions about this item

What server backplane or adapter is required for the U.2 15mm form factor?

A U.2 15mm bay or an adapter that accepts a 2.5-inch 15mm drive and provides a PCIe 4.0 x4 link is required for the D7-P5520 to operate.

Will the PCIe 4.0 x4 interface run at full speed on a PCIe 3.0 backplane?

The drive will operate on a PCIe 3.0 backplane but sequential read and write speeds will be limited to the 3.0 bandwidth ceiling.

How can I verify the drive delivers the rated 1,000,000 random read IOPS after installation?

Run a 4K random read benchmark at queue depth 32 or higher and confirm sustained IOPS approaching 1,000,000 with the drive at steady state.
