P400

Reviewer verdict

Across 14 YouTube reviews, the Patriot P400 earns an Index score of 3.7/5, ranking #57 among SSDs. Reviewers most often praise its performance, price, features, while the most common criticisms concern performance, power consumption.

The Patriot P400 is repeatedly praised for strong real-world performance, with many reviewers (37 mentions) reporting very fast sequential and 4K results, benchmark wins, and speeds often exceeding the manufacturer's promises. Reviewers also frequently highlight its value, noting an aggressive, budget-friendly price point (18 mentions) that positions it as one of the cheapest Gen4 options and a compelling cost‑to‑performance choice. Additional positive points mentioned by multiple reviewers include included or effective thermal features and extras (8 mentions) such as a heatsink/graphene thermal pads and useful bundled materials, plus broad compatibility and practical capacities suitable for PC and PlayStation 5 use (combined mentions across compatibility and capacity).

Criticism is concentrated on performance degradation under sustained fill and high occupancy: many reviewers (19 mentions) observed significant write slowdowns as the drive fills (notably past three‑quarters full) and reduced small‑block/write performance, making some say they would not use it as a system disk. Several reviewers (8 mentions) also raised thermal and power concerns, reporting high temperatures, throttling under load, and skepticism that the supplied graphite/graphene radiator or heatsink always copes effectively. A smaller set of reviewers pointed out that the drive does not fully exploit PCIe 4.0 peak throughput and that some heatsink/thermal features may be lacking or ineffectual, and a few noted price/delivery variances.
