Data-center capacity

The Solidigm D7-P5520 delivers 15.36TB in a U.2 15mm form factor built for read-intensive server workloads. It uses 144L TLC 3D NAND and a PCI-Express 4.0 x4 interface to serve high-capacity storage tiers.

Thermals and power

Enterprise U.2 drives are designed for forced-air chassis cooling rather than onboard fans. The 15mm height fits standard 2.5" hot-swap bays with adequate airflow. Power draw scales with the PCIe 4.0 x4 link and the 7100 MBps sequential read ceiling.

Endurance rating

A 2,000,000 hour MTBF and Opal security define the reliability envelope for always-on arrays. The drive withstands 1,000 G shock at .5 msec and 2.17 GRMS operating vibration. Buyers needing higher write endurance or a different form factor should evaluate other models.

Questions about this item

How do I install the U.2 15mm drive in a 2.5-inch bay and what step is often missed?

Mount the drive in a U.2 15mm backplane or carrier, connect the PCI-Express 4.0 cable, then enable the drive in the server BIOS or RAID controller before the OS will see it.

What maintenance or replacement will the 144L TLC 3D NAND need over its life?

The drive has no user-serviceable parts; plan replacement when the media reaches its rated endurance or when SMART health indicators show critical wear.

What limit appears first during sustained writes on this 15.36TB model?

Sequential write speed tops out at 3700 MBps; thermal throttling may engage before that ceiling under continuous heavy workloads.
