Enterprise capacity for read-heavy workloads
The Solidigm D7-P5520 delivers 7.68TB of storage in an E1.S 9.5mm form factor built for data-centre servers. It uses 144L TLC 3D NAND with a PCI-Express 4.0 x4 interface to reach 6600 MBps sequential read and 4200 MBps sequential write. Random performance hits 1100000 IOPS read and 220000 IOPS write at 4K blocks. Endurance is rated at 14.0 PBW with a 2000000-hour MTBF.
Hot-plug E1.S tray simplifies installation
The drive slides into a compatible E1.S 9.5mm bay and locks with the built-in latch, so no cables or screws are required. Power draw peaks at 18W active and 5W idle, which standard server backplanes handle without extra cooling. The 72g weight and 1000 G shock rating mean vibration in dense chassis rarely causes issues. Opal encryption is hardware-based and activates through the management console.
Verify E1.S 9.5mm bay and PCIe 4.0 support
Confirm the server chassis has an E1.S 9.5mm slot wired for PCI-Express 4.0 x4; narrower or taller bays will not accept the drive. Check that the backplane supplies up to 18W per slot and that the BIOS or firmware recognises Opal security features. The operating vibration spec of 2.17 GRMS at 5-700 Hz assumes a properly secured tray in a rated enclosure.

Questions about this item
How do I verify the D7-P5520 is performing at its rated 6600 MBps sequential read and 1100000 IOPS random read after installation?
Run a benchmark such as FIO or CrystalDiskMark against the PCIe 4.0 x4 link; expect up to 6600 MBps sequential read and 1100000 IOPS 4K random read if the slot and cooling meet spec
What ships with the SSDPFUKX076T1OS and what must I source separately?
The single pack contains only the 7.68TB E1.S 9.5mm drive; you must supply a compatible E1.S backplane or carrier, PCIe 4.0 cabling, and any mounting screws
Which capacity and form-factor version of the D7-P5520 should I select for a 7.68TB E1.S 9.5mm slot?
Choose part number SSDPFUKX076T1OS; it is the 7.68TB model built in the E1.S 9.5mm form factor for PCIe 4.0 x4 servers
