The PNY XLR8 CS3040 is a PCIe 4.0 x4 NVMe drive in the standard M.2 2280 size, rated at up to 5,600 MB/s read and 3,900 MB/s write. It is a DRAM-less design, so it leans on host memory buffering and a dynamic SLC cache, which keeps it quick in everyday use but can slow on very large sustained writes. The 4TB capacity is the draw: a single drive for a game library or media project without juggling volumes. It suits PS5 expansion and desktop builds on a budget, but it trails premium Gen4 drives like the Samsung 990 Pro and WD Black SN850X on peak speed and endurance rating.

Owners rate it highly, mostly for the capacity and the speed jump over older SATA and Gen3 drives. Complaints center on write speed dropping during very large transfers and on the lack of a heatsink.
