The Crucial P3 Plus is a budget PCIe 4.0 NVMe SSD that trades speed consistency for capacity per dollar. It uses QLC flash and has no onboard DRAM, which is how it reached a 4TB model at a low price. Crucial's parent company has also exited the consumer market, so availability is a bigger question than it was at launch.

What published reviews found
Tom's Hardware described the P3 Plus as a capable first attempt at a faster budget drive, but said QLC still has drawbacks. Its testing showed performance that was middling next to TLC drives at similar prices, and it noted that the endurance rating of 200 to 220TBW per terabyte trails competitors such as Solidigm's P41 Plus.
PC Gamer looked at the 2TB model and was more critical. Its sequential tests came in under 5GB/s, well short of what premium Gen4 drives reach, and its PCMark 10 Storage score fell below 2,500 points compared with roughly 3,500 for top drives. The outlet reported that the drive holds peak write speed for about 500GB before the SLC cache runs out, after which writes dropped to around 90MB/s. It suggested paying about $30 more for Crucial's TLC-based P5 Plus, saying "the savings from this QLC drive just aren't enough."
StorageReview ran database-style workloads on the 4TB model and ranked it near the bottom in several of them, including last place in 4K random write. Its 64K sequential write result was the one chart where the drive finished first. StorageReview also criticized Crucial for not clearly disclosing the QLC flash, and it did not recommend the drive.
GamesRadar's 4TB sample was friendlier. It measured about 5,009MB/s reads and 4,332MB/s writes, slightly above the rated figures, and copied a 54GB game install at roughly 2.45GB/s. It called the drive good value but unexciting, noted that it has no heatsink, and pointed buyers toward the P5 Plus successor.
Across the outlets, the pattern is consistent: fine while the cache lasts, then a steep drop on large sustained writes.
Price and availability
Tom's Hardware listed launch MSRPs of $59.99 (500GB), $99.99 (1TB), $189.99 (2TB), and $399.99 (4TB). GamesRadar later reported 4TB retail prices well above that MSRP, so launch pricing is not a reliable guide today.
Micron announced that it would stop supplying Crucial-branded consumer products by the end of February 2026 and said it would keep honoring warranties and support for existing products, according to Tom's Hardware. That means any new P3 Plus you find is likely leftover retail stock or a third-party listing. Street prices change often, so check current listings and confirm who is selling the drive before you buy. Our SSD deals page tracks current offers.
Who it's for
The P3 Plus suits someone who needs a lot of space for installed games and mostly reads from the drive. In published tests it behaves like a decent bulk game drive as long as writes stay modest. It is also a reasonable secondary drive for a budget gaming PC build.
Skip it if you move large files often, record or edit video to the same drive, or want predictable write speeds. In that case, a TLC drive such as the Samsung 990 EVO Plus or the WD Black SN770 holds speed better, and both are covered in our other buyer's guides. If the 4TB price is the only appeal and the street price has climbed near TLC territory, the case for QLC weakens quickly.
Bottom line
The Crucial P3 Plus was a low-cost way to reach 2TB and 4TB on PCIe 4.0, and published reviews agree that its everyday read speeds are fine. They also agree that write performance and endurance lag TLC rivals, and one major outlet would not recommend it at all. With Crucial's consumer line winding down, buy it only if the price per terabyte is clearly lower than comparable TLC drives, and treat it as a read-heavy game library drive.
