The Crucial P310 is a solid-state drive in the M.2 2230 form factor, launched on July 17th, 2024. It is available in capacities ranging from 1 TB to 2 TB. This page reports specifications for the 2 TB variant. With the rest of the system, the Crucial P310 interfaces using a PCI-Express 4.0 x4 connection. The SSD controller is the PS5027-E27T from Phison, a DRAM cache is not available. Crucial has installed 232-layer QLC NAND flash on the P310, the flash chips are made by Micron. To improve write speeds, a pseudo-SLC cache is used, so bursts of incoming writes are absorbed more quickly. The cache is sized at 400 GB. Copying data out of the SLC cache (folding) completes at 320 MB/s. Thanks to support for the fast PCI-Express 4.0 interface, performance is excellent. The P310 is rated for sequential read speeds of up to 7,100 MB/s and 6,000 MB/s write; random IO reaches 1000K IOPS for read and 1200K for writes.
At its launch, the SSD was priced at 215 USD. The warranty length is set to five years, which is an excellent warranty period. Crucial guarantees an endurance rating of 440 TBW, a relatively low value compared to other SSDs.
