Crucial P310 2TB PCIe 4.0 x4 NVMe M.2 2230

The Crucial P310 is a 2TB M.2 2230 NVMe SSD built for handhelds like the Steam Deck and ROG Ally. It delivers 7,100 MB/s reads and 6,000 MB/s writes in a compact form factor, with a 5-year warranty. It runs hot under sustained load and costs more than full-size drives, but for 2230 upgrades it's one of the best options available.

Sequential reads top out at 7,100 MB/s and writes at 6,000 MB/s, which puts this drive in the 81st percentile for speed in our database. That's strong, especially for a 2230 drive. Random read IOPS hit 1,000K, which lands in the 86th percentile. In practice, game loads on a Steam Deck feel snappy, and boot times drop noticeably compared to the stock drive most handhelds ship with.

But there's a catch. This is a DRAM-less drive, and while Crucial's controller does a good job keeping things moving, sustained heavy writes can get toasty. Multiple owners report the drive hitting 86°C under load, and a few mention thermal throttling during big file transfers or extended gaming sessions. If you're planning to hammer this thing with sustained writes, grab a thin heatsink. For typical handheld gaming bursts, it's fine. The drive also gets limited by Gen3 interfaces on older devices, so if your handheld or laptop tops out at PCIe 3.0, you'll see roughly half the advertised speed. Still fast, just not the full 7,100 MB/s.

The Samsung 9100 Pro is the obvious heavyweight here, but it's a full-size 2280 drive with a DRAM cache and higher endurance. If your device fits 2280, the Samsung is the better pure performer. The WD Black SN850X is another strong 2280 alternative with a proven track record and often better pricing. Both of those will beat the P310 in sustained workloads thanks to their DRAM caches.

Where the P310 wins is form factor. None of those competitors come in 2230. The Kingston Fury Renegade and Seagate FireCuda 530R are also 2280 drives, so they're not even in the running for Steam Deck or Surface upgrades. If you need 2230, the P310 is competing against a much smaller field, and it's one of the fastest options available in that size. The trade-off is thermal behavior and the DRAM-less design, but for handheld gaming those matter less than raw sequential speed and capacity.

At USD 299 to USD 353, the P310 isn't a budget drive, but it's not outrageous either. The USD 299 listing is the one to grab if you're buying today. Compare that to full-size 2TB Gen4 drives, which often land closer to USD 150 to USD 200, and you're paying a solid premium for the 2230 form factor. That's the trade-off. If your device takes a standard 2280 drive, skip this and save the cash. But if you need 2230, your options are limited, and the P310 is one of the better values in that space. The 440 TBW endurance rating is about average, but for a handheld gaming drive that's more than enough. Most people will never come close to that before upgrading their device.

The Crucial P310 is a 2TB M.2 2230 NVMe SSD aimed squarely at handheld gamers and anyone stuck with a compact laptop or mini PC. It's a PCIe 4.0 drive with a DRAM-less design and TLC NAND, and it sits in a weirdly specific niche: tiny form factor, big capacity, and speeds that would have been flagship territory a couple years ago. If you're shopping for a Steam Deck SSD upgrade or an ASUS ROG Ally SSD, this is one of the first drives people point to, and for good reason.

Pricing is a bit scattered right now. We're seeing USD 299 to USD 353 across three US listings, with the best deal at USD 299. That's not cheap for a 2TB drive, but you're paying a premium for the 2230 form factor. Full-size 2280 drives with similar specs often undercut this by a decent margin, but they won't fit in a Steam Deck or Surface without a hacksaw and a bad attitude.

Crucial backs this with a 5-year warranty and a 440 TBW endurance rating. That's middle of the pack for endurance, but for a handheld gaming drive it's plenty. Most people will replace the device before they wear out the SSD.

Skip the P310 if your device takes a standard 2280 drive. You'll pay a premium for the 2230 form factor and give up the DRAM cache that full-size drives like the Samsung 9100 Pro or WD Black SN850X offer. Also skip it if you're doing heavy sustained writes, like video editing or constant large file transfers. The DRAM-less design and thermal behavior make it a poor fit for that workload. And if you're on a tight budget, the price premium over 2280 drives is hard to justify when a USD 150 full-size drive will outperform this in most scenarios.

If you're upgrading a Steam Deck, ROG Ally, or Surface and need 2TB in a 2230 form factor, the Crucial P310 is an easy recommendation. It's fast, reliable, and backed by a solid warranty. The thermal concerns are real but manageable, and for typical handheld gaming sessions you won't notice them. The price premium over 2280 drives stings, but that's the cost of fitting 2TB into a drive the size of a postage stamp.

Should you buy this? If your device requires 2230, yes. It's one of the best options in that category right now. If your device takes a standard 2280 drive, no. You'll get better performance and lower prices from the Samsung 9100 Pro or WD Black SN850X. The P310 is a specialist's drive, and for its specialty it's excellent.
