Team Group MP44Q 4TB PCIe 4.0 x4 NVMe M.2 2280

4TB of fast PCIe 4.0 storage with a DRAM-less catch. Great for bulk storage, less great for boot drives.

Sequential reads hit 7400 MB/s and writes land at 6200 MB/s, which is fast enough to make most PCIe 3.0 drives look like they're standing still. But the random performance is where the DRAM-less design shows its hand. It sits at the 62nd percentile for random operations, which is fine but not exciting. One verified owner clocked real-world reads closer to 6500 MB/s on an X570 board, so don't expect to hit the marketing numbers every time. The 2000 TBW endurance rating is genuinely impressive for QLC, and the 1.6 million hour MTBF is a nice confidence booster. The graphene label does a decent job keeping thermals in check, but it's not a replacement for a real heatsink if you're hammering it with sustained writes.

The MP44Q goes up against some heavy hitters. The Samsung 9100 PRO is the obvious premium alternative, with better random performance and a more established track record, but you'll pay for it. The Western Digital Black SN850X is the enthusiast favorite, with a DRAM cache and consistently strong performance across the board. The Crucial T500 is probably the closest competitor in terms of price and capacity, and it has a DRAM cache, which gives it an edge in random workloads. The Kingston FURY Renegade G5 and Seagate FireCuda 530R are also in the mix, but they're more niche picks. If you're building a gaming rig and want the best overall experience, the SN850X or T500 are safer bets. If you just need a ton of storage and don't care about DRAM, the MP44Q holds its own.

At $499 to $510 USD, this is not a budget drive. The affordability percentile is 18th, which means you're paying a premium for the 4TB capacity and the Team Group name. But when you look at what you get, 4TB of PCIe 4.0 storage with a 2000 TBW endurance rating and a 5-year warranty, the value proposition starts to make sense. It's not the cheapest 4TB drive out there, but it's also not the most expensive. If you need a lot of fast storage and don't want to deal with multiple drives, this is a reasonable way to get there.

The Team Group MP44Q 4TB is a big, fast slab of storage that mostly delivers on its promises. You get 4TB of QLC NAND in a standard M.2 2280 form factor with a graphene heat spreader slapped on top. The headline numbers are 7400 MB/s read and 6200 MB/s write, which puts it near the top of the PCIe 4.0 charts. But here's the thing: it's DRAM-less, and that shows up in some real-world quirks. For a bulk storage drive or game library, it's a solid pick. For a boot drive, you might notice the difference.

If you're building a system where this will be your only drive, especially a boot drive, skip it. The DRAM-less design and reported boot quirks from PCIe slots make it a less reliable choice for that role. Go grab a WD Black SN850X or Crucial T500 instead. If you're on a tight budget, this isn't the drive for you either, the affordability percentile is 18th, so there are cheaper 4TB options out there.

The Team Group MP44Q 4TB is a good drive with a few asterisks. It's fast, it's capacious, and it's backed by a solid warranty. But the lack of DRAM and the real-world speed shortfall mean it's not the best choice for every use case. If you're using it as a secondary drive for games, media, or bulk storage, it's a great pick. If you're planning to boot from it or run heavy random workloads, you might want to look at something with a DRAM cache. For most people, this drive will do exactly what they need, and do it well.
