Crucial 4TB SSD PCIe 4.0 NVMe M.2 2280

The Crucial P310 4TB is a big, fast, honest Gen4 drive that punches above its weight in random performance. Just don't expect flagship endurance from QLC NAND, and shop around because the price swings wildly.

Sequential speeds land right where Crucial promises, and our database puts this drive well above average for Gen4 speed. The 1,000K random read and write IOPS are the real surprise here. That's a standout result for a DRAM-less QLC drive, and it translates to snappy game loads and quick app launches. The catch is that you need a PCIe 4.0 slot to see those numbers. Drop it into a Gen3 system and you'll still get a solid upgrade, but you're leaving a lot on the table. The heatsink version does its job too, keeping thermals in check during long PS5 sessions without turning into a jet engine.

The WD Black SN850X is the obvious rival here. It's faster in sustained writes, has DRAM, and typically costs a bit more, but it's the better pick if you're moving huge files constantly. The Samsung 9100 PRO is in a different league entirely, Gen5 speeds and a price tag to match, so it's only worth considering if your motherboard supports it and your wallet doesn't mind. The Kingston FURY Renegade G5 and Seagate FireCuda 530R both offer similar Gen4 performance with better endurance ratings, but they're usually pricier per gigabyte. For pure capacity-per-dollar at Gen4 speeds, the P310 holds its own.

Pricing is all over the place right now, from $519 to $795 across US retailers. At the low end, this is a genuinely good deal for 4TB of Gen4 speed. At the high end, you're paying flagship money for a mid-tier drive and should look elsewhere. Shop around, and if you can snag it near $519, the value proposition is hard to beat. The 5-year warranty sweetens the deal, especially since Crucial's support is actually responsive when things go wrong.

The Crucial P310 4TB is a big, fast, no-nonsense Gen4 drive that nails the basics and skips the fluff. The headline here is simple: 7,100 MB/s reads and 6,000 MB/s writes in a 4TB package that slots into laptops, desktops, and even a PS5 without drama. It's not trying to be a flagship benchmark monster, and that's fine. For most people, this is the drive to buy when you want a ton of fast storage and don't want to think about it again for five years.

What makes it interesting is the mix. You get QLC NAND and no DRAM cache, which usually makes us wince, but Crucial's G8 NAND and firmware tuning keep real-world performance surprisingly snappy. The 800 TBW endurance rating is the trade-off for that 4TB capacity at this price, and we'll get into whether that matters for you.

If you're a content creator or anyone who moves massive files around daily, this isn't your drive. The QLC NAND and DRAM-less design mean sustained write speeds drop hard once the cache fills. Go get a WD Black SN850X or a Samsung 9100 PRO instead. You'll pay more, but you'll actually get the endurance and consistency your workload needs.

Buy the Crucial P310 4TB if you want a big, fast, reliable drive for gaming, everyday use, or PS5 expansion, and you can find it near the $519 mark. The QLC endurance trade-off is real but overblown for most people. If you're writing hundreds of gigabytes daily, get the SN850X instead. For everyone else, this is a straightforward win.
