Crucial P310 4TB PCIe Gen4 NVMe SSD
4TBPCIe Gen4 x4 NVMeUp to 7,100MB/sM.2 2280
The Crucial P310 4TB, part number CT4000P310SSD8, is a high-capacity PCIe Gen4 internal M.2 2280 NVMe SSD with reads up to 7,100MB/s, ideal for adding a large amount of fast solid-state storage to a desktop or laptop. From Crucial (the consumer brand of Micron), it pairs Micron 3D NAND with the efficient Phison E27T controller, offering near-flagship Gen4 speed and a huge 4TB at an accessible price.
With sequential reads up to 7,100MB/s, writes up to 6,000MB/s and random performance up to 1,000K/1,000K IOPS, the P310 makes a fast, spacious boot or storage drive. Carrying EAN 0649528942258 and MPN CT4000P310SSD8, this DRAM-less (HMB) model is rated for 800TBW with a 1.5 million-hour MTTF and a 5-year limited warranty. Typically in stock with fast delivery across Cyprus.
Compatibility note
The P310 needs an M.2 2280 slot — 22mm wide and 80mm long — with an NVMe PCIe key. It works in PCIe Gen4 and Gen3 slots (at the slot’s speed) and its single-sided design fits most recent laptops and desktops. It will not work in SATA-only M.2 slots. Confirm your system supports 4TB before ordering.

Frequently Asked Questions
Will the P310 fit my laptop or desktop?
It uses the standard M.2 2280 size with an NVMe PCIe slot, which fits most laptops and desktops from the last several years. Its single-sided design also suits thin laptops. Check your manual for an "M.2 2280 PCIe/NVMe" slot.
How fast is it compared with a SATA SSD?
Much faster — up to 7,100MB/s versus around 550MB/s for SATA. You will notice quicker boots, faster game loads and snappier large file transfers, making it an excellent upgrade.
Is 4TB and a value Gen4 drive enough for me?
For everyday computing, gaming and media the P310 feels very fast, and 4TB comfortably holds a large mixed library. As a QLC, DRAM-less drive it is best for typical use; for sustained heavy professional writes a high-end TLC drive would hold up better.
What does QLC and DRAM-less mean for performance?
The P310 uses QLC NAND with Host Memory Buffer instead of an onboard DRAM cache. For everyday use, gaming and General storage the real-world difference is small, and it keeps a 4TB drive affordable.
Singular Expert Insight
The Crucial P310 is a smart-value Gen4 drive, and the 4TB is the pick for those who want a large, fast NVMe at a sensible price: near-flagship 7,100MB/s speed with the trust of the Crucial/Micron name and a 5-year warranty. Its QLC NAND and DRAM-less design mean a high-end TLC drive like the Samsung 990 PRO holds up better under sustained heavy writes, but for everyday use, gaming and big media libraries the P310 feels just as fast for far less.

Buyer's Guide
Buy it if
You want a fast, affordable 4TB Gen4 NVMe drive for a laptop or desktop, as a roomy boot or storage upgrade for a big game and media library, with a 5-year warranty.
Skip it if
You do sustained heavy writes (large video editing, constant cloning) where a DRAM, TLC drive holds up better, or you need maximum Gen4/Gen5 peak speed.
Also consider
The Crucial P310 in smaller capacities to save money, the Lexar NQ790 for another value 4TB, or the Samsung 990 PRO for a top-tier TLC Gen4 drive.
