The Patriot P400 is a PCIe 4.0 x4 M.2 2280 solid state drive built on a DRAM-less controller with 3D NAND, aimed at budget-conscious builds and storage upgrades. Sequential reads reach around 7,000 MB/s, putting it in the same class as other entry PCIe 4.0 drives, though sustained writes and random performance trail premium drives with a DRAM cache. It suits gamers, media hoarders and secondary-storage upgrades where capacity matters more than peak benchmark numbers. Reviewers treat it as a value pick, not a top-tier boot drive for heavy workstation loads.

Owners and reviewers describe the P400 as a solid value NVMe drive that hits advertised sequential speeds in short bursts. Most praise easy installation and the large capacity for the money. Critics note that heavy sustained writes expose the DRAM-less design, with speeds dropping after the SLC cache is used up.
