Enterprise read-intensive SSD
The Solidigm D5-P5316 is a 30.72TB enterprise solid-state drive built for read-heavy data-centre workloads. It fits servers and storage arrays that need maximum capacity in a standard 2.5-inch U.2 15mm bay. The drive uses 144L QLC 3D NAND and connects via PCI-Express 4.0 x4. It is suited for content delivery, analytics and archival tiers where write cycles are low.
PCIe 4.0 x4 interface
The PCI-Express 4.0 x4 connection is the single specification that determines compatibility. The host system must provide a U.2 backplane or adapter wired for four lanes of PCIe 4.0 to achieve the rated 7000 MBps sequential read and 3600 MBps sequential write. Without a PCIe 4.0 x4 link the drive will negotiate a slower speed and not deliver its published throughput.
30.72TB capacity and endurance
At 30.72TB the drive stores massive datasets such as video libraries, object stores or backup repositories with room to spare. Endurance is rated at 22.93PBW for 64K random writes and 104.55PBW for 64K sequential writes, giving years of headroom for read-dominant workflows. Sustained heavy random writes will consume the write budget faster and are not the intended use case.

Questions about this item
What does the 30.72TB capacity mean for a server workload?
The 30.72TB capacity lets you store massive datasets on a single 2.5" U.2 15mm drive, reducing the number of drives needed for high-density read-intensive storage.
What does the PCIe 4.0 x4 interface cap in practice?
The PCIe 4.0 x4 interface supports up to 7000 MBps sequential read and 3600 MBps sequential write, with 800000 IOPS random read and 510 MB/s random write.
What physical space and power does the 15mm U.2 drive need to fit and run?
It requires a 2.5-inch bay that accepts 15mm Z-height drives and a U.2 backplane, drawing 5W idle and 25W active within a 0°C to 70°C operating range.
