Crucial SSD PCIe 4.0 NVMe M.2 2230

The Crucial P310 is a 1TB M.2 2230 SSD built for handheld gaming PCs, hitting 7,100 MB/s read speeds that rival full-size drives. It's a massive upgrade for Steam Deck or ROG Ally owners running out of space, with a 4.8/5 rating from over 2,000 reviews. Prices range from $199 to $300, so shop around before you buy. If you need a 2230 drive, this is one of the best options out there.

Let's talk about those numbers. 7,100 MB/s sequential read and 6,000 MB/s write are the headline specs, and they're legit. That puts the P310 in the 82nd percentile for speed across all SSDs in our database, which is well above average. For context, that's faster than a lot of full-size Gen4 drives from a couple years ago. The random read performance is also solid at 1,000K IOPS, landing in the 87th percentile. That matters more than sequential speeds for everyday use, since loading games and launching apps involves lots of small file reads scattered across the drive.

Real-world implications? Game load times on a Steam Deck or ROG Ally will feel snappy. You won't be waiting around for levels to load, and moving a 50GB game from internal storage to this drive should be quick. The DRAM-less design is worth mentioning though. Without a DRAM cache, the drive relies on HMB (Host Memory Buffer) to keep things moving, which works fine on Windows and most modern systems. Under sustained heavy writes, like copying hundreds of gigabytes at once, you might see speeds dip as the QLC NAND fills up. For most handheld gaming use, that's not a scenario you'll hit often. The endurance rating of 220 TBW is middle of the pack at the 69th percentile, which is fine for a gaming drive but not something you'd want to use as a write-heavy scratch disk.

The Samsung 990 PRO is the elephant in the room. 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 Steam Deck or ROG Ally without an adapter, and adapters are a pain. The P310's whole reason for existing is that it fits where the 990 PRO physically cannot. If you're building a desktop or upgrading a laptop with a full-size M.2 slot, the 990 PRO or the Western Digital BLACK SN850X are better choices. Both have DRAM caches and TLC NAND, which means better sustained performance and higher endurance.

The Kingston Fury Renegade is another full-size competitor with similar specs to the 990 PRO. Again, it's not a 2230 drive, so it's not really competing for the same slot. The Team Group MP44 is interesting because it comes in larger capacities and is often cheaper, but it's also a 2280 drive. For the handheld gaming niche, the P310's real competition is other 2230 drives like the WD Black SN770M or the Corsair MP600 Mini. The P310 beats most of those on paper with its 7,100 MB/s read speed, and the customer reviews back that up with a 4.8/5 rating across 2,072 reviews.

Here's where things get interesting. The P310 is listed anywhere from $199 to $300 in the US, which is a $101 spread depending on where you shop. That's a huge gap for the same drive. If you can find it at the lower end of that range, it's a solid deal for a 1TB Gen4 2230 drive. At $300, you're paying a premium for the form factor, and that's harder to justify when you could get a full-size 2TB Gen4 drive for similar money.

The value proposition really depends on what you're upgrading. If you have a Steam Deck with a 64GB or 256GB drive and you're constantly juggling game installs, the P310 is a massive quality-of-life improvement. The price-to-performance ratio at $199 is genuinely good for what you're getting. At $300, you're in enthusiast territory, and you might want to wait for a sale or look at other 2230 options. The affordability percentile sits at 43rd, which means it's not a budget drive by any stretch, but it's not outrageously priced either.

The Crucial P310 is one of those drives that exists for a very specific reason. It's a 1TB M.2 2230 SSD, which is the tiny form factor that fits in handheld gaming PCs like the Steam Deck, ASUS ROG Ally, and MSI Claw. Most people don't think about storage upgrades until they run out of space, and with modern games routinely eating 100GB or more, that happens fast on a 512GB handheld. The P310 solves that problem without asking you to compromise on speed.

What makes this drive interesting is that it's pushing PCIe Gen4 speeds in a package that used to be limited to much slower SATA or older NVMe drives. Crucial claims 7,100 MB/s read and 6,000 MB/s write, which puts it right up there with full-size desktop drives. For a 2230 drive, that's genuinely impressive. The social proof is also off the charts, sitting in the 95th percentile across our database, which means a lot of people have bought this thing and most of them are happy.

But here's the thing. This is a QLC drive with no DRAM cache. That's the trade-off you're making. QLC NAND is cheaper to produce but typically has lower endurance and can slow down under sustained writes. Crucial counters with a 220 TBW rating and a 5-year warranty, which is decent for QLC. The question is whether the real-world performance holds up when you're actually installing games and moving large files around, not just hitting peak numbers in a benchmark.

If you're building a desktop PC or upgrading a laptop with a full-size M.2 2280 slot, skip this drive. You're paying for the compact 2230 form factor, and you can get better sustained performance, higher endurance, and more capacity from a TLC drive with DRAM for the same money. The Samsung 990 PRO, WD Black SN850X, or Kingston Fury Renegade are all better choices for full-size slots.

Also skip it if you do a lot of heavy write workloads, like video editing or running a database. The QLC NAND and DRAM-less design mean sustained writes will slow down significantly once the SLC cache fills up. For that kind of work, look for a TLC drive with a DRAM cache and a higher TBW rating. And if you're on a tight budget and just need basic storage for a handheld, there are cheaper 2230 options out there that sacrifice some speed but cost less.

If you own a Steam Deck, ROG Ally, or MSI Claw and you're tired of deleting games to make room for new ones, the Crucial P310 is an easy recommendation. The 1TB capacity is a sweet spot for handheld gaming, and the speed is genuinely impressive for a 2230 drive. You'll notice faster load times and less time staring at loading screens. The install process is straightforward, and Crucial's 5-year warranty gives you peace of mind.

For desktop users, this drive makes less sense. You're paying for the compact form factor, and you can get more capacity and better sustained performance from a full-size drive for the same money. The QLC NAND and lack of DRAM are real compromises that don't matter much in a handheld but become more noticeable in a desktop workload. If you're building a gaming PC, get a TLC drive with DRAM like the 990 PRO or SN850X. If you're upgrading a handheld, the P310 is one of the best options available right now.
