Samsung 870 QVO 1TB SATA III 2.5"

The 870 QVO is a cheap, high-capacity SATA drive that's great for reading and rough for writing. Buy it for storage, not for speed, and only if you find it under USD 110.

Sequential speeds are right at the SATA limit, 560 MB/s read and 530 MB/s write, so you're getting everything the interface can give you. Random performance is where things get honest. 98K random read IOPS and 88K random write IOPS land this drive in the middle of the pack, around the 44th percentile for random and 38th for speed overall. That's fine for everyday use, but it's not going to impress anyone who's used to a decent NVMe drive. The QLC NAND means sustained writes drop hard once the SLC cache fills up. One owner put it bluntly: great for heavy reading, terrible for heavy writing. If you're moving hundreds of gigabytes regularly, you'll feel it. For normal people doing normal things, it's quick enough that you won't think about it.

The 870 QVO sits in a weird spot. Against the Crucial T500 or Western Digital WD_BLACK SN7100, both NVMe drives, the QVO gets smoked on raw speed. But those drives aren't SATA, so if you're upgrading an older machine without an M.2 slot, they're not even options. The more honest comparison is against Samsung's own 870 EVO. The EVO uses TLC NAND, which means better sustained writes and higher endurance, but it costs more. If you're just storing games or media, the QVO is fine. If you're doing anything write-heavy, the EVO is worth the extra cash. The Micron T710 and MSI SPATIUM M480 PRO are both NVMe drives that make the QVO look ancient on paper, but again, different form factor, different use case.

Value is a weird one here. The price spread across US vendors is wild, anywhere from USD 98 to USD 358 for the same 1TB drive. At the low end, this is a no-brainer for bulk SATA storage. At the high end, you're getting robbed. Newegg has the best deal right now at USD 98, and that's the only price that makes sense. The 870 QVO is a budget drive, and it only works as a budget drive. Pay more than about USD 110 and you should be looking at a TLC drive with better endurance instead.

The Samsung 870 QVO is the drive you buy when you need a lot of cheap SATA storage and you're done pretending every drive needs to be an NVMe speed demon. It's a 1TB 2.5-inch SATA III SSD with QLC NAND, a DRAM cache, and Samsung's MKX controller. The headline numbers are 560 MB/s read and 530 MB/s write, which is basically the ceiling for SATA. But the real story is endurance and sustained write behavior. At 360 TBW and a 1-year warranty, this is not a drive for heavy write workloads. For a game library, media storage, or breathing life into an old laptop, it's a solid pick. Just don't expect it to hang with TLC drives when the cache runs dry.

If you're doing heavy video editing, constant large file transfers, or running a database, this isn't your drive. The QLC NAND and 360 TBW endurance will bite you. Go get a TLC drive like the Samsung 870 EVO or a decent NVMe drive with better sustained write performance instead. This is a storage drive, not a workhorse.

The Samsung 870 QVO is a good drive for a specific job: cheap, high-capacity SATA storage that mostly gets read. It's not a performance drive, and it's not built for heavy writes. The 360 TBW endurance and 1-year warranty are the weak points, and the QLC NAND means sustained write performance is genuinely bad once the cache fills. But for a game library, a media drive, or reviving an old laptop, it's hard to beat at the right price. Just make sure you're paying the right price. USD 98 from Newegg is a deal. USD 358 is a scam.
