Enterprise capacity for dense servers

The Solidigm D7-P5520 is a 7.68TB enterprise SSD built in the E1.S 15mm form factor for high-density server and data-centre deployments. It connects via PCI-Express 4.0 x4 and uses 144L TLC 3D NAND to deliver large capacity in a slim profile suited to 1U and EDSFF chassis.

Sustained throughput and endurance

Sequential reads reach up to 6600 MBps and writes up to 4200 MBps, while random performance is rated at 1100000 IOPS read and 220000 IOPS write at 4K blocks. The drive is rated for 14.0 PBW of writes and an MTBF of 2,000,000 hours, with active power draw of 18W and idle draw of 5W to maintain steady output under continuous load.

Rugged build with Opal security

The 84g drive operates from 0°C to 70°C and withstands 1,000 G shock at .5 msec plus 2.17 GRMS operating and 3.13 GRMS non-operating vibration. Its E1.S 15mm connector enables hot-plug installation in tool-less cages, and hardware-based Opal encryption secures data at rest without host software overhead.

Questions about this item

How much power does the D7-P5520 draw when running active workloads all day?

The drive consumes 18W during active operation and 5W at idle, so sustained workloads will draw the higher figure continuously.

What slot type is required to install this E1.S 15mm SSD?

You need an EDSFF E1.S 15mm bay with a PCI-Express 4.0 x4 electrical connection; standard M.2 or U.2 slots will not accept this form factor.

Will the PCI-Express 4.0 x4 interface work in a PCIe 3.0 backplane without losing functionality?

The drive is backward compatible with PCIe 3.0 slots, operating at 3.0 speeds while retaining full Opal security and 14.0 PBW endurance.
