Built for dense server storage

The Solidigm D7-P5520 is a 3.84TB enterprise SSD in the E1.S 15mm form factor. It uses 144L TLC 3D NAND and a PCI-Express 4.0 x4 interface. The drive targets data-centre workloads that demand high capacity and consistent throughput in a compact slot.

E1.S slot efficiency

The 15mm E1.S design fits hot-plug bays built for high-density chassis. An idle draw of 5W and an active ceiling of 15W keep thermal load predictable. Opal security is supported on the controller. The unit weighs 84g and is rated for 1,000 G shock at 0.5 msec.

Replaces older enterprise drives

Sequential reads reach 6500 MBps and writes reach 3400 MBps. Random performance delivers 1000000 IOPS read and 147000 IOPS write at 4K blocks. Endurance is rated at 7.0 PBW with a 2,000,000-hour MTBF. The jump is worth it when moving from lower-endurance or PCIe 3.0 drives that cannot sustain these IOPS levels.

Questions about this item

What maximum throughput does the PCIe 4.0 x4 interface cap this drive at in practice?

The PCIe 4.0 x4 interface supports up to 6500 MBps sequential read and 3400 MBps sequential write for this 3.84TB model.

What physical slot and clearance does the E1.S 15mm form factor require?

It fits an E1.S 15mm bay and weighs 84g with a tolerance of +/- 5g, so the chassis must accept that height and weight.

How is the drive installed in a server, and which step is often missed?

Insert the drive into the hot-plug E1.S cage until the latch engages, then verify the Opal security setting is enabled in the BIOS before use.
