15.36TB U.2 enterprise SSD

The Solidigm D7-P5520 is a 15.36TB U.2 15mm enterprise solid state drive built for data centre and server workloads. It uses 144L TLC 3D NAND and a PCI-Express 4.0 interface to deliver up to 7100 MBps sequential read and 3700 MBps sequential write speeds. The drive weighs 165g and carries a 2,000,000 hour MTBF rating.

Suited to high-capacity read-heavy deployments

This drive suits operators who need a single 15.36TB device for read-intensive applications and can accommodate a 15mm U.2 bay with PCIe 4.0 connectivity. Buyers who need a thinner 7mm form factor, a different capacity point, or a drive optimised for write-heavy endurance should look at other models.

PCI-Express 4.0 x4 interface

The drive connects through a PCI-Express 4.0 x4 link, so the host backplane or adapter must support that interface and provide a U.2 15mm slot. Systems limited to PCIe 3.0 or lacking a compatible U.2 connector cannot use this SSD at its rated performance.

Questions about this item

How can I verify the drive is healthy after installation without interrupting I/O?

The drive reports health status over PCIe and SMBus while I/O continues, so you can monitor SMART attributes or vendor tools during normal operation.

What accessories are included and what must be sourced separately?

The single pack contains only the 15.36TB U.2 15mm drive; a compatible U.2 backplane or cable, mounting bracket and power are not included.

Which capacity and form-factor version of the D7-P5520 should I select for a 2.5-inch U.2 bay?

Choose the 15.36TB U.2 15mm model (SSDPF2KX153T1N1) — it fits a 2.5-inch U.2 slot and delivers up to 7100 MBps read and 3700 MBps write over PCIe 4.0 x4.
