Overview

A flash controller and NVMe interface connect this drive straight to the motherboard, while a heatsink covers the board to pull heat away. Gamers use it to store large game libraries on a desktop or in a Sony console.

Very high sequential speeds suit game loading and large file work. The heatsink is a plus in a console slot or open desktop board, but its height can block low-clearance slots such as those in laptops.

Who it's for

A desktop builder or console owner who wants a large NVMe drive with cooling already attached. Someone with a tight laptop bay should check clearance first. Buyers with an older SATA-only machine cannot use it.

Pros and cons

Pros

Very high read speed
Heatsink already attached
Supports Sony console slots
Dashboard software available

Cons

Heatsink adds height
Write speed listed two ways
Dashboard software is Windows only
Cache size unit missing

Performance notes

Sequential speeds this high depend on a motherboard or console slot that supplies enough PCIe lanes, and slower slots cap the result. Under long writes the controller heats up, which is where the heatsink helps hold speed. Everyday loading times depend more on random access than on the headline sequential figure.
