Capacity and form factor

The Solidigm D7-P5520 is a 15.36TB enterprise SSD built in a U.2 15mm 2.5" form factor. It uses 144L TLC 3D NAND and a PCI-Express 4.0 x4 interface for data-centre workloads. The drive carries a 2,000,000-hour MTBF rating and supports Opal security.

Host compatibility checks

Verify that your server or storage array provides a U.2 15mm drive bay with a PCI-Express 4.0 x4 electrical connection. Confirm the backplane supplies the required power and that the system firmware recognises 15.36TB devices. Ensure the operating system or hypervisor includes a driver for Solidigm enterprise SSDs.

Build integration

The 15mm height fits standard 2.5" U.2 hot-swap trays, freeing 3.5" bays for other uses. Opal encryption offloads security processing from the CPU. The drive tolerates 1,000 G shock at 0.5 msec and 2.17 GRMS operating vibration, reducing the need for additional dampening in dense racks.

Questions about this item

Does the 15.36TB U.2 15mm drive ship with a heatsink or mounting bracket?

The drive is supplied as a bare U.2 15mm module; any heatsink, carrier or mounting hardware must be sourced separately to fit your server chassis.

When should I pick the 15.36TB 144L TLC model over a lower-capacity D7-P5520?

Choose the 15.36TB version when you need maximum read-intensive capacity per U.2 slot; smaller capacities in the same series share the PCIe 4.0 x4 interface and 144L TLC NAND but offer less total space.

What does the 2,000,000-hour MTBF mean for a server running 24/7?

The MTBF rating indicates a very high expected reliability for continuous operation; combined with 1,000 G shock and 2.17 GRMS operating vibration tolerance, the drive is built for demanding data-centre workloads.
