Form factor and capacity

The Solidigm D7-P5520 is a 3.84TB enterprise SSD in the E1.S 15mm form factor. It uses 144L TLC 3D NAND and connects through a PCI-Express 4.0 x4 interface. The drive weighs 84g and is built for continuous operation in server and data-centre environments.

Fit for purpose

This drive suits operators who need high random-read performance and a 7.0 PBW endurance rating for read-intensive workloads. It is not for systems that only accept 2.5-inch U.2 or M.2 modules, nor for buyers who require hardware-based encryption such as TCG Opal support.

Deciding specification

The E1.S 15mm form factor is the single specification that determines whether this SSD can be installed. Verify that your chassis and backplane explicitly support E1.S 15mm drives before purchasing.

Questions about this item

How is the E1.S 15mm form factor installed, and what step is commonly missed?

Insert the drive into the hot-plug E1.S cage until the latch clicks, then secure the retention screw; the step often missed is tightening that screw, which keeps the PCIe 4.0 x4 connection stable under vibration.

What maintenance or replacement will the 144L TLC 3D NAND need over its service life?

No field maintenance is required; the drive is replaced once the 7.0 PBW endurance budget is consumed or the 2,000,000-hour MTBF rating is reached, whichever comes first.

What limit appears first during sustained writes on this 3.84TB drive?

The sequential write ceiling of 3400 MBps is reached before the 15W active power limit or the 1,000 G shock threshold become factors.
