Team Group MS30 2TB SATA III M.2 2280

Cheap 2TB SATA storage with a catch: it's DRAM-less, freezes randomly for some users, and sits in the bottom 5 percent of our sentiment data. Buy it only if you need bulk storage you don't care about losing.

Sequential reads top out around 550 MB/s and writes at 500 MB/s, which is fine for SATA III but puts it in the bottom quarter of all drives we've tested. The lack of onboard RAM cache means sustained writes can stutter, and our random performance data lands this thing in the bottom 20 percent. One reviewer actually measured 530 MB/s reads, slightly better than advertised, but that's not the story. The story is the freezing. Multiple owners report 2-8 second lockups during basic reads and writes. That's not a benchmark issue, that's a usability problem.

The Western Digital Black SN850X and Samsung 9100 PRO are in a completely different league, with NVMe speeds and DRAM caches that make the MS30 look like it's running on dial-up. But those cost more and need PCIe slots. The real comparison is against other budget SATA M.2 drives, and even there, the MS30's reliability complaints put it behind options from Crucial and Kingston that cost about the same. If you can stretch to an NVMe drive, do it. The MS30 is a last resort for SATA-only systems.

At $239 to $260 USD, this is not the screaming deal it looks like. You can find NVMe drives with DRAM caches and far better reliability for similar money. The MS30 only makes sense if you're stuck with a SATA-only M.2 slot and you absolutely need 2TB on a tight budget. Even then, cross your fingers.

The Team Group MS30 is a budget M.2 SATA drive that promises 2TB for not much cash. But here's the thing: it's DRAM-less, the endurance rating is mediocre, and our user sentiment data puts it in the bottom 5 percent of all drives we track. That's not a typo. Some folks get a cheap, simple storage upgrade. Others get random freezes and a drive that shows signs of failure within a month. This is a gamble, not a sure thing.

If you're looking for a reliable boot drive or anything you'll write to frequently, this isn't it. Go grab a Crucial MX500 or a WD Blue 3D NAND instead. They cost a bit more but won't freeze on you mid-write. The MS30 is only for people who need cheap bulk storage in a SATA-only M.2 slot and can accept the risk.

Don't buy this as a boot drive. Don't buy it for anything you care about. The MS30 is a cheap storage drive for files you can afford to lose, and even then, the freeze reports are concerning. If you need reliable 2TB SATA storage, spend a bit more on a drive with a DRAM cache and a better track record. This one's a pass for most people.
