This page reports specifications for the 1 TB variant. With the rest of the system, the Crucial P3 Plus interfaces using a PCI-Express 4.0 x4 connection. The SSD controller is the PS5021-E21T from Phison, a DRAM cache is not available. Crucial has installed 176-layer QLC NAND flash on the P3 Plus, the flash chips are made by Micron. To improve write speeds, a pseudo-SLC cache is used, so bursts of incoming writes are soaked up more quickly. The cache is sized at 250 GB. Copying data out of the SLC cache (folding) completes at 100 MB/s. Thanks to support for the fast PCI-Express 4.0 interface, performance is excellent. The P3 Plus is rated for sequential read speeds of up to 5,000 MB/s and 3,600 MB/s write.
At its launch, the SSD was priced at 100 USD. The warranty length is set to five years, which is an excellent warranty period. Crucial guarantees an endurance rating of 220 TBW, a relatively low value compared to other SSDs.
