Form factor and capacity

This Solidigm D7-P5520 is a 7.68TB enterprise SSD built in the E1.S 15mm form factor for dense server deployments. It uses 144L TLC 3D NAND and a PCI-Express 4.0 x4 interface to deliver high throughput in data-centre environments. The drive weighs 84g and is rated for 2,000,000 hours MTBF.

Suitable workloads and limitations

It suits read-heavy applications such as content delivery, analytics and warm-tier storage where the 14.0 PBW endurance rating matches the workload. The 1100000 IOPS random read and 6600 MBps sequential read support high concurrency. Buyers who need higher write endurance or sustained write bandwidth for write-intensive logging or OLTP should look at drives with a higher PBW rating.

Deciding specification

The single figure that decides fit is the 14.0 PBW endurance rating combined with the 220000 IOPS random write and 4200 MBps sequential write. If your workload writes more data than this endurance allows, the drive will wear out before its service interval. Verify your daily write volume against this number before purchase.

Questions about this item

What E1.S slot height and PCIe generation does the D7-P5520 require?

The drive uses the E1.S 15mm form factor and connects through a PCI-Express 4.0 x4 interface.

Which way does the E1.S connector key orient when inserting the 15mm drive?

Align the E1.S edge connector with the slot key notch and press straight in until the latch clicks; forcing it at an angle can bend the PCIe 4.0 pins.

When should the 7.68TB D7-P5520 be replaced based on its rated endurance?

The drive is rated for 14.0 PBW of writes; plan replacement once the SMART media-wear indicator approaches that limit.
