Solidigm D7-P5620 6.4TB U.2 15mm enterprise SSD

The Solidigm D7-P5620 is a 6.4TB enterprise solid-state drive built in a U.2 15mm form factor. It connects through a PCI-Express 4.0 interface and uses 144L TLC 3D NAND. The drive is designed for data centre and server workloads that demand consistent high throughput and endurance.

Suited for write-intensive server workloads.

This drive suits environments that require sustained mixed read and write performance with 35.0 PBW endurance. Buyers whose workloads are read-heavy or capacity-focused without the need for high write endurance should evaluate lower-cost alternatives.

35.0 PBW endurance rating

The drive delivers 35.0 PBW of write endurance backed by a 2,000,000-hour MTBF. Active power draw reaches 18W while idle consumption is 5W. This endurance figure is the primary metric for matching the drive to workload lifetime requirements.

Questions about this item

Should I choose the 6.4TB U.2 15mm version or a smaller capacity?

The 6.4TB U.2 15mm model delivers 35.0 PBW endurance and 18W active power, suited for write-intensive server workloads needing maximum capacity in a single 2.5-inch bay.

What does the 7100 MBps sequential read mean for my database server?

That 7100 MBps read speed lets a PCIe 4.0 x4 host pull large datasets into memory faster, reducing query latency on read-heavy OLAP or logging workloads.

How does the PCIe 4.0 x4 interface limit real-world throughput?

The PCIe 4.0 x4 link caps sustained transfers near 7100 MBps read and 4200 MBps write; heavier queues hit the 1100000 IOPS random read or 390000 IOPS random write ceiling first.
