Patriot P300 M.2 PCIe Gen 3 x4 512GB Low-Power Consumption SSD | Interface: PCIe Gen 3 x4; Low-power design.

Status: Patriot P300 M.2 PCIe Gen 3 x4 512GB Low-Power… (512GB PCIe 3.0 NVMe SSD): Unavailable on Amazon as of . SpecPicks has no in-stock 512GB PCIe 3.0 NVMe SSD on file; an Amazon search for "512GB PCIe 3.0 NVMe SSD" lists current offers with the same specs. eBay sellers may still list this model new or used.

Bottom line: The Patriot P300 M.2 PCIe Gen 3 x4 512GB Low-Power Consumption SSD: 1,700MB/s read and 1,100MB/s write, roughly 3x SATA SSD speed; main trade-off: SMI 2263XT is a DRAM-less controller, so random performance trails DRAM drives.

Pros & Cons

Pros

  • ✓ 1,700MB/s read and 1,100MB/s write, roughly 3x SATA SSD speed
  • ✓ 5 year warranty on a budget-tier NVMe drive
  • ✓ LDPC plus SmartECC and end-to-end data path protection
  • ✓ Built-in thermal throttling guards against sustained-load overheating

Cons

  • ✗ SMI 2263XT is a DRAM-less controller, so random performance trails DRAM drives
  • ✗ Gen 3 x4 caps throughput well below Gen 4 and Gen 5 drives
  • ✗ 512GB fills fast with 100GB+ modern game installs
  • ✗ 1,100MB/s write is the slower half of the read/write pair

Manufacturer description

The Patriot P300 512GB is an entry-level NVMe drive built for people upgrading from SATA without overspending. It uses an SMI 2263XT DRAM-less controller on a 2280 M.2 PCIe Gen 3 x4 interface with NVMe 1.3 support, delivering sequential reads up to 1,700MB/s and writes up to 1,100MB/s, plus 4K aligned random writes up to 260K IOPS. That is roughly three times the sequential throughput of a SATA SSD, so boot times, game level loads, and application launches all tighten up noticeably. Patriot builds in end-to-end data path protection, SmartECC, and LDPC error correction, which catches and…

SpecPicks Verdict

SpecPicks scored Patriot P300 M.2 PCIe Gen 3 x4 512GB 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 512GB?

Sequential reads reach up to 1,700MB/s and writes up to 1,100MB/s, with 4K aligned random writes up to 260K IOPS on the PCIe Gen 3 x4 interface.

Will this fit my motherboard?

It is a 2280 M.2 form factor drive using PCIe Gen 3 x4 with NVMe 1.3, so it fits any standard M.2 2280 NVMe slot. Confirm your slot is NVMe rather than SATA-only.

What warranty does Patriot offer on the P300?

Patriot lists a 5 year warranty on this drive. Check the product listing for current registration and claim terms.

Does the P300 have DRAM cache?

It uses the SMI 2263XT Series controller, which is a DRAM-less design. Data integrity is handled through LDPC error correction, SmartECC, and end-to-end data path protection instead.

Which operating systems does it support?

Patriot lists Windows 8.1, 10, and 11 as supported, with Windows 7 and 8.0 noted with an asterisk. NVMe 1.3 compliance means Linux and other NVMe-aware systems generally recognize it.
