Solidigm D7-P5520 3.84TB U.2 enterprise SSD

This Solidigm D7-P5520 is a 3.84TB enterprise solid-state drive built for data-centre servers. It uses a U.2 15mm form factor and connects through a PCI-Express 4.0 interface with 144L TLC 3D NAND. The drive carries a 2,000,000-hour MTBF rating and supports Opal security encryption.

Suits high-capacity server storage.

This drive suits administrators who need high-capacity, reliable storage for server arrays and heavy read workloads. Builders working in standard desktop chassis or laptops should look elsewhere because the U.2 15mm form factor requires specific backplane support and physical clearance not found in consumer systems.

Deciding spec: U.2 15mm form factor with PCIe 4.0 x4

The single specification that decides fitment is the U.2 15mm form factor combined with the PCI-Express 4.0 interface. Your server backplane must accept a 15mm-thick 2.5-inch U.2 drive and provide a PCIe 4.0 x4 link; without that exact mechanical and electrical match the drive cannot be installed or will run at reduced capability.

Questions about this item

What sustained write workload hits the drive endurance limit first?

The 3.84TB drive uses 144L TLC 3D NAND rated for 2000000 hours MTBF under enterprise workloads.

How much heat does the U.2 15mm drive add to a server running all day?

The PCIe 4.0 x4 interface and 144L TLC NAND operate within standard enterprise thermal envelopes for 2.5 inch 15mm bays.

Which server backplane connector must my chassis provide for this drive to work?

The drive requires a U.2 backplane that accepts a 15mm 2.5 inch form factor and supplies PCIe 4.0 x4 signalling.
