15.36TB U.2 15mm Enterprise SSD

The Solidigm D7-P5520 is a 15.36TB enterprise solid-state drive in a U.2 15mm form factor. It connects via a PCI-Express 4.0 interface and uses 144L TLC 3D NAND. The drive delivers sequential reads up to 7100 MBps and writes up to 3700 MBps. It is rated for 28.0 PBW endurance with a 2,000,000-hour MTBF.

Suited for read-intensive data centre workloads

This drive suits servers and storage arrays that prioritise high-capacity read performance and FIPS security compliance. It is not for systems limited to thinner 7mm or 9mm drive bays, nor for platforms that cannot accept a 15mm Z-height. Buyers needing higher random write IOPS or lower active power draw should evaluate alternatives.

PCIe 4.0 x4 interface requirement

The SSD requires a PCIe 4.0 x4 electrical connection through a U.2 backplane or adapter to achieve its rated throughput. Verify that the host platform provides this link width and the physical 15mm clearance before purchase.

Questions about this item

Should I choose the 15.36TB U.2 15mm version or a smaller capacity for my server?

The 15.36TB capacity suits read-heavy workloads needing maximum space per drive bay; smaller capacities in the same D7-P5520 series would reduce both storage density and the 28.0 PBW endurance rating proportionally.

What does the 7100 MBps sequential read figure mean once the drive is installed in a real server?

That 7100 MBps is the PCIe 4.0 x4 interface limit for large-block reads; actual throughput depends on your CPU lane allocation, queue depth, and whether the workload sustains long sequential transfers or shifts to the 1000000 IOPS random-read profile.

The drive uses PCIe 4.0 — what does that cap in practice?

PCIe 4.0 x4 caps theoretical bandwidth at roughly 8 GBps, so the 7100 MBps read and 3700 MBps write ceilings are interface-bound; you will not exceed them even if the 144L TLC NAND could go faster.
