Form Factor and Interface

The Plextor M8Pe PX-256M8PeY is a 256GB internal solid-state drive built on an add-in card form factor. It connects through a PCI-Express 3.0 x4 interface using the NVMe protocol for high-speed data transfer.

Target Audience and Limitations

This drive suits users with a free PCIe x4 slot who want MLC endurance and a dedicated cooling fin design for sustained loads. Builders limited to M.2 slots or requiring higher capacities should consider other options.

Deciding Specification

The add-in card form factor is the single specification that determines compatibility; the drive must be installed in a full-size PCIe expansion slot rather than an M.2 connector.

Questions about this item

Will this drive fit in a standard PCIe x4 slot?

Yes, the AIC form factor plugs directly into any PCI Express 3.0 x4 slot and the card height is 22.39 mm.

Does the board need active cooling for this SSD?

The card includes built-in cooling fins designed for high-efficiency airflow, so no extra fan is required under normal loads.

What random read performance can I expect in real use?

The drive is rated for up to 210,000 IOPS 4 KB random read and up to 23,000 IOPS 4 KB random write.
