Crucial P310 1TB PCIe 4.0 x4 NVMe M.2 2230

The Crucial P310 brings serious Gen4 speed to the tiny 2230 form factor, with 7,100 MB/s reads and 1M random IOPS that put it near the top of our database. It's the best upgrade path for Steam Deck, ROG Ally, and MSI Claw owners who want 1TB without sacrificing performance. Prices range from USD 199 to USD 290, so shop around before you buy. If your device takes a standard 2280 drive, look elsewhere, but for 2230 users this is a top pick.

Let's talk about what those numbers actually mean when you're sitting on the couch waiting for a game to load. The 7,100 MB/s read speed is the headline, and it's legitimately fast for a Gen4 drive. In our database, that puts it in the 79th percentile for speed overall, which is strong but not chart-topping. The random read performance is where it really shines though. 1M IOPS is 84th percentile territory, and that's the metric that matters most for game loading and general snappiness. Games aren't one big file, they're thousands of small ones, and the P310 chews through them quickly.

The write speed of 6,000 MB/s is solid too, though you'll only see those numbers during big file transfers or game installs. The DRAM-less design means it relies on your system's memory for caching, which is standard for 2230 drives and helps keep power consumption in check. The trade-off is that sustained writes can dip once the cache fills up, but for gaming workloads that's rarely an issue. You're loading games, not editing 8K video on a Steam Deck.

One thing to keep in mind: this drive runs warm. The customer reviews mention it, and it makes sense when you're pushing this much performance through such a small package. In a handheld with limited airflow, that heat can translate to throttling during long transfers. For normal gaming sessions it shouldn't be a problem, but if you're planning to clone a full drive over, expect it to get toasty.

The 2230 market has gotten more crowded lately, but the P310 still stands out. Compared to the Samsung 9100 PRO, the Crucial drive holds its own on random reads but gives up some ground on features and endurance. Samsung's drives tend to come with better software and higher TBW ratings, but you'll pay for it. The Western Digital WD_BLACK SN7100 is another strong competitor with similar Gen4 speeds, and WD's gaming-focused branding means it's often priced aggressively. The Micron T710 is essentially a cousin of the P310 since Micron owns Crucial, so you're getting similar silicon with different branding.

The Lexar NM1090 PRO and ADATA GAMMIX S70 Blade are both solid Gen4 drives, but they're primarily available in the 2280 form factor. If your device can take a full-size drive, those are worth a look and often cheaper per gigabyte. But for 2230 specifically, the P310's combination of speed, capacity, and brand reliability is hard to beat. The main trade-off is heat and price. You're paying a premium for the small form factor, and you'll want to keep an eye on temperatures in tight enclosures.

Pricing on the P310 is all over the place right now. We're seeing USD 199 to USD 290 across four US listings, which is a USD 91 spread for the exact same drive. That's not a small difference. If you're paying USD 290, you're overpaying. If you can snag it at USD 199, that's a genuinely good deal for this level of performance in the 2230 form factor. The CAD 391 listing in Canada is harder to judge without more data points, but it's worth shopping around.

The value equation here is interesting because you're not just paying for storage, you're paying for the form factor. A standard 2280 Gen4 drive with similar specs would cost less, but it won't fit in your Steam Deck. The P310's real competition is other 2230 drives, and most of them are either slower or capped at lower capacities. When you factor in the 5-year warranty and 220 TBW endurance rating, the P310 justifies its price if you actually need the speed. If you just want more space and don't care about load times, there are cheaper 2230 options that will do the job.

The Crucial P310 is one of those drives that exists because handheld gaming finally got serious. The Steam Deck, ROG Ally, and MSI Claw all use the tiny M.2 2230 form factor, and for a long time your upgrade options were either slow, small, or both. The P310 changes that with a 1TB capacity and PCIe 4.0 speeds that would have looked impressive in a full-size desktop drive a couple years ago. It's a niche product, sure, but it's a niche full of people who are tired of deleting games to make room for new ones.

Crucial is positioning this as the GOAT of handheld storage, and the spec sheet backs up some of that swagger. You get 7,100 MB/s sequential reads and 6,000 MB/s writes, plus 1M random read IOPS. Those are numbers that put it in the 79th percentile for speed and 84th for random performance in our database. For a drive the size of a stick of gum, that's genuinely impressive. The DRAM-less design keeps power draw down, which matters when you're running off a battery.

Who is this for? Handheld gamers who want more storage without sacrificing load times, and laptop owners with 2230 slots, like certain Surface and Dell models. If you've got a standard 2280 slot, there are faster and cheaper options out there. But if your device demands the small form factor, the P310 is one of the best choices you can make right now.

If your device has a standard 2280 M.2 slot, there's no reason to buy the P310. Full-size Gen4 drives with similar or better specs are cheaper per gigabyte and run cooler thanks to more surface area. You'd be paying a premium for a form factor you don't need. Look at the WD_BLACK SN7100 or ADATA GAMMIX S70 Blade instead.

Also skip this if you're on a tight budget and just need more space. The P310's speed is impressive, but if you're mostly playing indie games or older titles, a slower 2230 drive will load them just fine and cost significantly less. The performance difference only really shows up with large, modern games. And if you're the type who does massive file transfers regularly, the DRAM-less design and thermal constraints might frustrate you. This is a gaming drive first and foremost.

If you own a Steam Deck, ROG Ally, or MSI Claw and you're still running the stock drive, the P310 is one of the easiest upgrades you can make. The 1TB capacity doubles or quadruples your storage, and the speed improvement over the drives these handhelds ship with is noticeable. Games load faster, and you'll spend less time staring at loading screens and more time actually playing. The install takes about five minutes if you're comfortable with a screwdriver.

For laptop users with 2230 slots, the calculus is similar. If you're stuck with a small drive and want more space without sacrificing performance, the P310 delivers. But if your laptop has a 2280 slot, skip this and get a full-size drive. You'll get more capacity for less money, and the thermal headroom is better. The P310 is a specialist, and it's excellent at what it does. Just don't buy it for a use case it wasn't designed for.
