3.84TB E1.S enterprise SSD

The Solidigm D7-P5520 is a 3.84TB enterprise solid-state drive built on 144L TLC 3D NAND. It uses the E1.S 9.5mm form factor and a PCI-Express 4.0 x4 interface for internal server and data-centre deployments.

Opal security and endurance

The drive includes Opal encryption for data-at-rest protection and is rated for 7.0 PBW of write endurance. Sequential reads reach up to 6500 MBps and writes up to 3400 MBps, with 1,000,000 random read IOPS and 147,000 random write IOPS.

E1.S slot and PCIe 4.0 support

Verify that your server or storage chassis provides an E1.S 9.5mm drive bay with a PCIe 4.0 x4 electrical connection. The drive draws 5W idle and 15W active, so confirm the backplane and cooling can deliver that power budget.

Questions about this item

How many petabytes can be written to the 3.84TB D7-P5520 before the endurance rating is reached?

The drive is rated for 7.0 PBW total bytes written across its warranty period.

Will the PCIe 4.0 x4 interface or the NAND flash hit its thermal limit first during sustained heavy writes?

Active power reaches 15W under load, so the controller and NAND package temperature will throttle before the PCIe 4.0 link saturates.

What is the typical power draw and resulting heat output when the E1.S 9.5mm drive runs continuously in a server?

Idle power is 5W and active power is 15W, so sustained operation produces heat equivalent to a 15W component.
