Bestoss GM528 2TB PCIe 4.0 NVMe M.2 2280

A solid, cool-running Gen4 drive that's easy to install and works great in older machines. But at $304, you're paying too much for a DRAM-less drive when faster options cost less.

The headline numbers are respectable. 5000 MB/s sequential reads land this drive in the top quarter of all NVMe drives we track, and the 4800 MB/s writes aren't far behind. But the random performance tells a more honest story. It sits just above the middle of the pack there, which is exactly what you'd expect from a DRAM-less design. The graphene-copper cooling sticker is a nice touch for PS5 use, and owners report it stays cool under load. What surprised us most is how well this drive works in older PCIe 3.0 machines. It won't hit max speed there, but it's still a massive upgrade over any SATA SSD.

The WD Black SN850X is the obvious benchmark here. It's faster, has DRAM, and usually costs less. The Crucial T500 is another strong alternative with better endurance and similar real-world performance. The Kingston Fury Renegade trades blows with the GM528 on speed but brings DRAM to the table. If you're shopping in this price range, the Bestoss only makes sense if you find it heavily discounted or you specifically want the graphene cooling for a PS5. Otherwise, the SN850X is the smarter buy.

Here's where it gets awkward. The GM528 is listed at $304 USD, and that's a tough sell when the Crucial T500 and WD Black SN850X regularly undercut it while offering DRAM and better endurance. The 37th percentile affordability score confirms it. If you catch this on sale, it's a fine buy. At full price, you're paying a premium for a drive that doesn't lead in any category.

The Bestoss GM528 is a 2TB PCIe 4.0 drive that plays it safe and mostly wins. You're getting 5000 MB/s reads and 4800 MB/s writes, which puts it in the upper-middle of the pack for Gen4 drives. It's not going to blow the doors off a WD Black SN850X, but for a boot drive or a game library in an older machine, it's a genuinely solid pick. The one thing to know? It's a DRAM-less TLC drive, so sustained writes will dip once the SLC cache fills up. For most people, that's a non-issue. For heavy video editors, it's worth knowing.

If you're doing serious video editing or moving huge files around all day, this isn't your drive. The DRAM-less design and below-average endurance will bite you under sustained load. Go grab a WD Black SN850X or Crucial T500 instead. And if you're looking for a portable drive, forget it. This thing scored a 17 out of 100 for portability, which is basically a polite way of saying it's not meant to leave your machine.

The Bestoss GM528 is a good drive that's priced like a great one. It installs easily, runs cool, and delivers solid Gen4 speeds that'll make any older PC feel new again. But at $304 for 2TB, you're paying flagship money for mid-pack performance. If you can grab it for $200 or less, go for it. At full price, buy the WD Black SN850X instead and don't look back.
