Capacity and Interface

The Solidigm D7-P5520 is a 3.84TB enterprise solid-state drive built on 144L TLC 3D NAND. It uses a U.2 15mm form factor and connects through a PCI-Express 4.0 x4 interface. The drive is rated for 7.0 PBW endurance and a 2,000,000-hour MTBF. It targets data-centre workloads that demand consistent read performance.

Workload Fit

This SSD suits servers handling read-intensive applications such as content delivery, web hosting or analytics where sequential reads reach 6700 MBps and random reads hit 1,000,000 IOPS. It is less suited for write-heavy databases or logging systems that exceed 3600 MBps sequential or 200,000 IOPS random write throughput. Buyers needing a thinner drive for 7mm bays should consider other form factors.

Deciding Specification

The U.2 15mm thickness is the single specification that determines compatibility. Only backplanes and drive cages designed for 15mm U.2 devices can accept this drive. Standard 7mm U.2 slots will not accommodate it. Verify the chassis or server specification for 15mm support before purchase.

Questions about this item

How can I confirm the D7-P5520 is delivering the rated 6700 MBps sequential read after installation?

Run a sequential read test with a tool such as FIO or CrystalDiskMark and compare the result to the specified 6700 MBps maximum.

What ships with the SSDPF2KX038T11Z and what must be sourced separately?

The drive itself is supplied in a single pack; a U.2 backplane, cabling and a PCIe 4.0 x4 slot are not included.

Which capacity of the D7-P5520 series should I choose for a write-heavy workload needing 7.0 PBW endurance?

This 3.84 TB model provides the 7.0 PBW endurance rating; other capacities in the series have different endurance figures.
