Crucial 1TB SSD PCIe 4.0 NVMe M.2 2230

The Crucial P310 is a 1TB Gen4 SSD in the tiny 2230 form factor, hitting 7,100 MB/s reads and 1,000K random read IOPS. It's built for Steam Deck, ROG Ally, and MSI Claw owners who want more storage without sacrificing speed. Pricing ranges from USD 199 to USD 290, so shop around. If you need a 2230 drive, this is one of the best options right now.

The headline numbers are legit. 7,100 MB/s sequential read and 6,000 MB/s sequential write put this drive well above average for Gen4 drives, and the random read performance lands in the 87th percentile. That's the metric that matters most for game loading and general snappiness. When you're booting up a big open-world game on a handheld, the drive isn't the bottleneck here. The CPU and thermal limits of the device will hold you back long before this SSD does.

But there's a catch. This is a DRAM-less QLC drive. That means sustained writes can dip once the SLC cache fills up. For typical handheld gaming use, you're mostly reading data, so it's not a huge deal. But if you're moving a 200GB game library over in one shot, you might see speeds drop after the first chunk. The endurance rating of 220 TBW is solid for a 1TB QLC drive, sitting in the 69th percentile. It's not going to win any longevity awards, but for a game drive that mostly reads data, it's fine.

The Samsung 990 PRO is the obvious comparison if you're looking at raw speed. It's a full-size 2280 drive with DRAM and TLC NAND, and it's faster in sustained workloads. But it won't fit in a handheld. The Kingston Fury Renegade is another strong Gen4 option, but again, it's a 2280 drive. If you're building a desktop or upgrading a laptop with a full-size slot, those are better choices. The P310 only makes sense if you specifically need the 2230 form factor.

For handheld owners, the real competition is other 2230 drives. The Lexar Professional NM1090 PRO and Team Group MP44 are both worth a look. The Lexar is a Gen5 drive, which is overkill for most handhelds but future-proof. The Team Group MP44 is often cheaper and offers similar real-world performance. The P310's advantage is that 7,100 MB/s read speed and the strong random read IOPS. If you're mostly loading games and not doing heavy writes, the P310 is the sweet spot.

Pricing on this drive is all over the place. In the US, we're seeing listings from USD 199 to USD 290, which is a USD 91 spread. That's a huge gap for the same 1TB drive. If you're shopping, check the retailer carefully. The best deal in our database comes from the US listings at the lower end of that range. At USD 199, this is a compelling buy for handheld owners. At USD 290, you're paying a premium for the form factor, and that's harder to justify.

Compared to the competition, the P310 sits in the 44th percentile for affordability. It's not cheap, but it's not outrageous either. The real value here is the combination of speed and size. You can find cheaper 2230 drives, but they won't hit these speeds. You can find faster full-size drives, but they won't fit in your Steam Deck. That's the trade-off, and for a lot of people, it's worth paying for.

The Crucial P310 is one of those drives that exists for a very specific person. If you own a Steam Deck, an ASUS ROG Ally, an MSI Claw, or one of those ultrabooks with the tiny M.2 2230 slot, you already know the struggle. Most fast drives are too big to fit. Most drives that fit are slow, boring, and built for office work. The P310 flips that on its head. It's a 1TB Gen4 drive in the 2230 form factor, rated for 7,100 MB/s reads and 6,000 MB/s writes. That's faster than a lot of full-size desktop drives from a couple years ago.

Crucial is leaning hard into the handheld gaming angle here, and honestly, it makes sense. The marketing copy is all about loading multi-world games, expanding your library, and keeping battery drain in check. The drive uses QLC NAND and skips the DRAM cache, which is the trade-off you make to hit this size and price. But the real-world numbers still look strong on paper, especially that 1,000K random read IOPS figure. For a drive this small, that's a standout.

We've got 2,072 customer ratings averaging 4.8 out of 5, which puts social proof in the 95th percentile. People seem genuinely happy with this thing. But the feature set is thin, and the endurance rating of 220 TBW is middle of the pack. So let's dig into what this drive actually does well, and where it falls short.

If you're building a desktop PC or upgrading a laptop with a full-size M.2 2280 slot, don't buy this. You're paying a premium for the small form factor, and you can get a faster drive with DRAM and TLC NAND for less money. The Samsung 990 PRO or Kingston Fury Renegade are better picks for that use case. Also, if you do heavy video editing or constantly move large files, the QLC NAND and lack of DRAM will frustrate you. Look for a TLC drive with a DRAM cache instead. And if you're on a tight budget, the Team Group MP44 or other budget 2230 drives will get you most of the way there for less cash.

If you own a Steam Deck, ROG Ally, or MSI Claw and you're tired of deleting games to make room, the Crucial P310 is an easy recommendation. The 1TB capacity is a huge upgrade over the stock 512GB drives most handhelds ship with, and the speed is genuinely impressive for a 2230 drive. Game loading times will drop noticeably, and the power efficiency claims seem to hold up based on what buyers are saying.

For desktop users or anyone with a full-size M.2 slot, skip this. You can get a faster drive with better endurance for less money. The P310 is a specialist product. It's not trying to be the best SSD on the market. It's trying to be the best SSD that fits in your handheld, and on that front, it succeeds.
