Enterprise E1.S 15mm drive

The Solidigm D7-P5520 is a 1.92TB enterprise SSD built for PCIe 4.0 x4 servers and storage arrays. Its E1.S 15mm form factor fits high-density hot-plug bays in modern data centres. It targets workloads that need consistent read performance and power-loss protection.

Capacity and headroom

1.92TB of 144L TLC 3D NAND delivers up to 5300 MBps sequential read and 1900 MBps sequential write. Random performance reaches 706000 read IOPS and 114000 write IOPS at 4K blocks. The 3.5 PBW endurance rating supports sustained write workloads, while sequential write throughput is the limiting factor for ingest-heavy pipelines.

Build quality and connectors

The single-sided E1.S 15mm module weighs 84g and mounts directly into tool-less EDSFF cages without cables. Opal security encrypts data at rest. Idle power is 5W and active power 13W within a 0°C to 70°C operating range. Shock tolerance of 1000 G and vibration ratings of 2.17 GRMS operating and 3.13 GRMS non-operating suit dense rack environments.

Questions about this item

Will the E1.S 15mm form factor fit in the same backplane slots as my existing E1.S drives?

Yes, the drive uses the standard E1.S 15mm form factor and PCI-Express 4.0 x4 interface, so it occupies the same physical slot and electrical connection as other E1.S 15mm devices.

How can I verify the drive delivers the rated 706000 random read IOPS after installation?

Run a 4K random read benchmark such as FIO with an appropriate queue depth; sustained results near 706000 IOPS confirm the controller and 144L TLC 3D NAND are performing to specification.

Does the single pack include a heatsink, mounting screws or a power cable, or must I source them separately?

The single pack contains only the SSD itself; any E1.S cage heatsink, retention screws or backplane power delivery must be supplied by the server chassis or purchased separately.
