PNY XLR8 CS3140 M.2 NVMe Gen4 SSD Review

There’s no shortage of ultra-fast storage these days, but that doesn’t mean to say there isn’t room for even more of it! The new PNY drives have landed, and as part of their high-end gaming range, XLR8, the new PNY XLR8 CS3140 promises some pretty impressive performance figures. Utilising the latest PCIe Gen 4 technology, you’ll need a compatible motherboard and CPU to take full advantage of what it has to offer. However, with read speeds of up to 7500 MB/s and write speeds of up to 5650 MB/s and that’s 6850 MB/s on the 2 TB model, it is certainly worth the investment, as this is promising to be one of the fastest consumer M.2 drives on the market today.


For next-gen consoles, your laptop, or your desktop PC, the PNY XLR8 CS3140 promises to be a god-like upgrade for many things. Since it’s the most common M.2 2280 form factor, it should be broadly compatible with most things too. However, keep in mind that PNY sells this drive on its own, with an SSD cover that would fit the PS5 (this is the version I have) and with a chunky heatsink, so be sure you pick the right version to suit your needs.


  • Available in 1TB, 2TB & 4TB
  • Sequential read speed of up to 7500 MB/s and write speed of up to 5650 MB/s
  • NVMe 1.4 Technology
  • M.2 2280 Form Factor
  • PCIe Gen4 x4
  • 3D Flash Memory
  • 2,000,000 Hours MTBF
  • 5 Years Warranty
