Pros & Cons

Pros

  • ✓ Up to 1600MB/s sequential read (CDM), roughly 3x a SATA SSD
  • ✓ Full PCIe Gen3 x4 lanes, not the x2 wiring budget drives use
  • ✓ NVMe 1.3 on a current-gen Gen3 controller
  • ✓ M.2 2280 fits standard desktop and laptop slots, no cables

Cons

  • ✗ 128GB fills fast; Windows plus a few apps is about the ceiling
  • ✗ Write speed tops out at 1000MB/s, below the read rating
  • ✗ Gen3 only, so no benefit from a Gen4 or Gen5 motherboard slot
  • ✗ Patriot lists Windows as the only supported OS

Manufacturer description

The Patriot P320 128GB is a PCIe Gen 3x4 NVMe SSD built for boot drives, cache volumes, and lightweight system builds where a small M.2 stick beats a mechanical drive on every metric that matters. Patriot rates it at up to 1600MB/s sequential read and up to 1000MB/s sequential write under CrystalDiskMark, which is roughly triple what a SATA drive delivers and a different world entirely from a spinning hard disk on startup and load times. It rides a current-generation PCIe Gen3 controller and speaks NVMe 1.3 across four lanes, so it sidesteps the bottleneck that Gen3 x2 drives run into under…

Frequently Asked Questions

How fast is the Patriot P320 128GB?

Patriot rates it at up to 1600MB/s sequential read and up to 1000MB/s sequential write as measured in CrystalDiskMark. Real-world speeds vary with your motherboard, thermals, and how full the drive is.

Will this fit my laptop?

It is an M.2 2280 module using the PCIe Gen3 x4 interface with NVMe 1.3, so it fits any laptop or desktop with a full-length 2280 M.2 NVMe slot. Check that your slot is NVMe and not SATA-only M.2 before buying.

Is 128GB enough for Windows?

It is enough for a Windows install plus a modest set of applications, which is the role this drive is built for. If you plan to store games, video, or large project files, pair it with a second drive or step up in capacity.

Does it work in a PCIe Gen4 motherboard?

Yes. PCIe is backward compatible, so the drive runs in a Gen4 or Gen5 M.2 slot at its Gen3 x4 speeds. You will not see any speed gain from the newer slot.

Does it work with Linux or macOS?

Patriot lists Windows as the supported operating system for the P320. Check the product listing or Patriot's support page for current compatibility details beyond Windows.
