7.68TB E1.S enterprise SSD

The Solidigm D7-P5520 delivers 7.68TB of capacity in the E1.S 9.5mm form factor. It connects over PCI-Express 4.0 x4 and uses 3D NAND TLC memory. The drive is built for data centre and server environments that need high-density storage in a compact footprint.

Capacity and endurance headroom

With 7.68TB of usable space the drive accommodates large datasets, virtualisation images and warm-tier workloads. Endurance is rated at 14.0 PBW, so sustained write traffic is supported until the written data approaches that threshold. Sequential reads reach 6600 MBps and writes 4200 MBps, while random performance tops out at 1,100,000 read IOPS and 220,000 write IOPS.

E1.S build and daily implications

The E1.S 9.5mm module weighs 72g and draws 5W idle or 18W active, fitting standard hot-plug cages without extra cabling. It operates from 0°C to 70°C and survives 1,000 G shock plus 2.17 GRMS operating vibration. Builders needing a 15mm or U.2 form factor, or a higher write-endurance tier, should look elsewhere.

Highlights

  • High capacity of 7.68TB supports large datasets

  • Sequential write up to 4200 MBps speeds up ingest workloads
  • Random read up to 1,100,000 IOPS handles heavy transactional traffic
  • 0 PBW endurance rating extends drive lifespan in write-intensive use

Questions about this item

Will the E1.S PCIe 4.0 x4 interface work in a server that only has U.2 PCIe 3.0 slots?

This drive uses an E1.S PCIe 4.0 x4 interface. It requires a compatible E1.S backplane or adapter; it cannot plug directly into a U.2 PCIe 3.0 slot without a physical and electrical converter.

How can I verify the 6600 MBps sequential read and 1100000 IOPS random read after installation?

Run a benchmark tool such as fio or CrystalDiskMark against the drive. Compare the measured sequential read and 4 KB random read results to the rated 6600 MBps and 1100000 IOPS figures.

Does the single pack include a heatsink, mounting screws or a PCIe adapter bracket?

The single pack contains the 7.68 TB E1.S drive only. Heatsinks, mounting screws and any PCIe adapter brackets are not included and must be sourced separately.
