Capacity and Form Factor

The Solidigm D7-P5520 is a 7.68TB enterprise solid-state drive built in a U.2 15mm form factor. It uses 144L TLC 3D NAND and connects through a PCI-Express 4.0 x4 interface. The drive is designed for data centre and server environments that need high-capacity internal storage.

Endurance Rating

The drive offers an endurance rating of 14.0 PBW, which determines how much data can be written over its warranty period. This figure is the primary spec for deciding whether the SSD matches a given write-intensive workload. Buyers who need more storage or higher write endurance should look at other capacities or models.

Power and Thermal Envelope

Active power draw reaches 18W while idle consumption sits at 5W, so the host system must provide adequate cooling for a 15mm U.2 bay. The operating temperature range spans 0°C to 70°C, and the drive tolerates 1,000 G shock at 0.5 msec. It fits standard 2.5-inch U.2 backplanes that accept 15mm z-height devices.

Questions about this item

What does the 7100 MBps sequential read figure mean once the drive is installed in a server?

In a PCIe 4.0 x4 slot the drive can sustain up to 7100 MBps for large-block reads, so backup windows and sequential analytics jobs finish faster than on a PCIe 3.0 device.

The drive uses a PCIe 4.0 x4 interface — what does that cap in practice?

The x4 link limits peak throughput to the PCIe 4.0 lane rate, so sequential reads top out at 7100 MBps and writes at 4200 MBps even if the controller could go higher.

What does the U.2 15mm form factor need to fit or mount in a 2.5-inch bay?

It requires a 2.5-inch drive bay that accepts a 15mm z-height U.2 connector and can supply up to 18W active power with adequate airflow for 0°C to 70°C operation.
