Patriot P300 M.2 PCIe Gen 3 x4 256GB Low-Power Consumption SSD

Bottom line: The Patriot P300 M.2 PCIe Gen 3 x4 256GB Low-Power Consumption SSD ($52.99 on Amazon as of 2026-10-20 16:15 UTC): Sequential reads up to 1,700MB/s - roughly 3x a SATA SSD; main trade-off: 256GB fills fast; one modern AAA game can eat half of it. Another in-stock pick with the same 256GB PCIe 3.0 NVMe: the XPG S40G 256GB RGB 3D NAND PCIe Gen3x4 NVMe 1.3…, $51.99 on Amazon as of (price may vary).

Pros & Cons

Pros

  • ✓ Sequential reads up to 1,700MB/s - roughly 3x a SATA SSD
  • ✓ 260K IOPS 4K random write keeps small-file work snappy
  • ✓ 5-year warranty, long for an entry-tier NVMe drive
  • ✓ LDPC plus NANDXtend ECC extends NAND flash lifespan

Cons

  • ✗ 256GB fills fast; one modern AAA game can eat half of it
  • ✗ Gen 3 x4 only - leaves Gen 4 and Gen 5 board speed unused
  • ✗ 1,100MB/s write trails the 1,700MB/s read noticeably
  • ✗ Mid-tier drive by Patriot's own positioning, not a flagship

Manufacturer description

The Patriot P300 256GB is a PCIe Gen 3 x4 NVMe M.2 drive built for people who want to move a boot volume off SATA without paying Gen 4 prices. Patriot rates it at sequential reads up to 1,700MB/s and writes up to 1,100MB/s, with 4K aligned random writes reaching 260K IOPS - enough headroom to cut Windows boot times and shorten level loads compared with a 2.5-inch SATA SSD capped near 550MB/s. Endurance and data integrity get real attention here: the P300 carries end-to-end data path protection, SmartECC, and LDPC with Patriot's NANDXtend ECC to stretch NAND flash lifespan, plus thermal…

SpecPicks Verdict

SpecPicks scored Patriot P300 M.2 PCIe Gen 3 x4 256GB Low-Power Consumption SSD using a rating × review-volume × price-fit model applied to published specs and reviews across the ssds & storage category. Patriot Memory's ssds & storage lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.

Common buyer scenarios for ssds & storage of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase. Prices and stock are set by the retailer and may have moved since this page was last updated.

Frequently Asked Questions

How fast is the Patriot P300 256GB?

Patriot rates it at sequential reads up to 1,700MB/s and sequential writes up to 1,100MB/s, with 4K aligned random writes up to 260K IOPS. That read figure is about three times what a SATA III SSD can deliver.

Will the P300 work in my PCIe Gen 4 motherboard?

It is a PCIe Gen 3 x4 NVMe M.2 drive, and Gen 4 slots are backward compatible, so it will run at its Gen 3 speeds. Confirm your board has an M.2 slot keyed for NVMe rather than SATA-only before buying.

What warranty does Patriot include?

Patriot lists a 5-year warranty on the P300. Check the product listing for current terms and registration requirements in your region.

Is 256GB enough capacity for a boot drive?

It is workable for Windows plus productivity apps and a couple of games. Windows 7 through 11 are supported. If you install large modern titles, plan on a second drive for your game library.

Does the P300 overheat in a laptop or small case?

It includes thermal throttling technology to protect the controller under sustained load, and Patriot markets the drive on low power consumption, which is why it is commonly used for notebook and small-form-factor upgrades.
