Capacity and role

The Solidigm D7-P5520 provides 3.84TB of enterprise storage in an E1.S 9.5mm form factor. It connects through a PCIe 4.0 x4 interface and uses 3D NAND TLC memory. The drive targets data-centre servers that need high-capacity, read-intensive storage in a dense, hot-pluggable bay.

Thermals and power

Idle power draw is 5W and active consumption reaches 15W. The rated operating range spans 0°C to 70°C. Vibration tolerance is specified at 2.17 GRMS (5–700 Hz) while running and 3.13 GRMS (5–800 Hz) when powered off. Shock resistance reaches 1,000 G at 0.5 msec.

Build and connectors

The E1.S module weighs 72g ± 5g and fits standard EDSFF S slots for tool-less insertion. Endurance is rated at 7.0 PBW with an MTBF of 2,000,000 hours. The single-pack shipment contains the drive only; brackets or cables are not included.

Questions about this item

How do I install the E1.S 9.5mm form factor drive into a server backplane and what step is commonly missed?

Slide the drive into the E1.S bay until the connector seats fully, then secure the single retention screw to lock it in place; the step often missed is tightening that screw, which ensures proper electrical contact and vibration resistance.

What maintenance or replacement will the 3D NAND TLC memory require after heavy write workloads?

The drive is rated for 7.0 PBW total bytes written; once that endurance limit is reached the NAND can no longer guarantee data integrity and the SSD must be replaced.

At what point does the 15W active power limit throttle sustained write performance?

When the controller hits the 15W active power ceiling during prolonged writes, it reduces write speed to stay within the thermal envelope, making power the first bottleneck under sustained load.
