Capacity and interface

The Solidigm D7-P5520 is a 1.92TB enterprise solid-state drive in a U.2 15mm form factor. It connects through a PCI-Express 4.0 x4 interface using 144L TLC 3D NAND. Sequential reads reach up to 6600 MBps and writes up to 4200 MBps.

Suitable workloads

This drive suits data-centre servers that need high endurance and consistent low-latency performance. It is not suited for desktop PCs or laptops that lack U.2 backplanes and PCIe 4.0 support. Buyers who need a smaller physical size or a different connector should look at other form factors.

Deciding specification

The U.2 15mm physical format is the single specification that determines whether this drive fits the target system. The host must provide a compatible U.2 bay with 15mm clearance and a PCIe 4.0 x4 link to use the drive at its rated speed.

Questions about this item

Which capacity and form factor of the D7-P5520 should I select for a 2.5-inch U.2 bay?

This model is the 1.92TB version in a U.2 15mm 2.5-inch form factor, matching bays that accept 15mm drives.

What do the 6600 MBps read and 4200 MBps write figures mean for my server workloads?

Those are maximum sequential speeds over PCIe 4.0 x4; real-world throughput depends on queue depth, block size and controller firmware.

Does the PCIe 4.0 x4 interface limit performance compared to newer standards?

The drive uses PCI-Express 4.0 x4, so peak bandwidth is capped at the 4.0 lane rate; it will not exceed that ceiling.
