High-capacity E1.L enterprise SSD

The Solidigm D5-P5316 provides 15.36TB of storage in a 9.5mm E1.L form factor using PCIe 4.0 x4 connectivity. It is built for data-centre operators who need dense, read-optimised flash for warm-tier workloads. The drive employs 144-layer QLC 3D NAND to deliver high capacity at a lower cost per terabyte than TLC alternatives.

Capacity and performance headroom

Sequential reads reach up to 7000 MBps while writes peak at 3200 MBps, giving fast access to large datasets. The 15.36TB capacity lets a single 1U chassis scale toward petabyte-level storage density. Write-heavy or sustained random workloads will exhaust the QLC endurance budget faster than TLC drives.

Upgrade path from hard drives and earlier SSDs

The SSD replaces 2.5-inch hard drives and previous-generation solid-state storage to cut latency and rack space. The jump is worthwhile when consolidation, read throughput and power efficiency matter more than maximum write endurance. Buyers needing higher write durability or smaller form factors should evaluate other models.

Questions about this item

Will the E1.L 9.5mm form factor fit alongside my existing 2.5" U.2 drives in the same server?

The drive uses the EDSFF E1.L 9.5mm form factor which is physically different from 2.5" U.2 drives. It requires a server chassis and backplane specifically designed for E1.L modules.

How can I verify the PCIe 4.0 x4 link is active and delivering the rated 7000 MBps sequential read speed?

Check the link width and speed in your OS or BIOS (should show PCIe 4.0 x4), then run a sequential read benchmark such as fio; sustained reads near 7000 MBps confirm the link is operating correctly.

Does the single pack include a heatsink, mounting bracket or power cable for the E1.L slot?

The single pack contains only the SSD itself. E1.L drives are powered and cooled through the backplane connector, so no separate cables or heatsinks are included or required.
