Lenovo D7-P5520 3.84 TB U.2 NVMe drive

This Lenovo D7-P5520 solid-state drive provides 3.84 TB of capacity in a 2.5 inch internal form factor. It connects through a U.2 interface using PCI Express 4.0 x4 NVMe. The drive is built for read-intensive server workloads and carries a 1 DWPD endurance rating with 7168 TB total bytes written.

Suited for read-heavy server deployments

This accessory fits servers that accept 2.5 inch U.2 NVMe drives and need high sequential throughput of 6860.80 MB/s. It is not intended for environments requiring write-intensive endurance or higher drive writes per day. Buyers needing a different physical connector or heavier write durability should consider other options.

Questions about this item

Will the U.2 NVMe 4.0 x4 interface work with my existing PCIe 3.0 backplane?

The drive uses a U.2 connector with PCIe 4.0 x4 signalling. It will operate at PCIe 3.0 speeds when installed in a PCIe 3.0 backplane, providing up to the 3.0 link bandwidth.

How can I verify the drive is healthy after installation?

Check SMART attributes for media wear indicator, total bytes written against the 7168 TB endurance rating, and confirm sequential read speeds approach 6860.80 MB/s under load.
