Samsung 860 QVO 1TB SATA III 2.5"

The 860 QVO maxes out SATA III at 550 MB/s read, and owners love it with a 4.8-star average. But 360 TBW endurance and a 3-year warranty are half what you get from Samsung's own 860 EVO. At $250+, it's a tough sell unless you catch a discount.

550 MB/s sequential read and 520 MB/s write is basically maxing out the SATA III interface. You won't squeeze more from this connection. Random performance is 96K read IOPS and 89K write IOPS, which puts it at 43rd percentile in our database. That's middle of the pack, and honestly fine for everyday use, but it's not going to impress anyone who's seen a modern NVMe drive.

The DRAM cache helps keep things snappy during normal workloads, and the 1TB capacity means you've got room for a decent game library or a pile of 4K video. Samsung claims 4x faster boot times than a spinning hard drive, and that tracks with what owners report. It's a night-and-day upgrade from an HDD, just don't expect NVMe-level responsiveness.

Against the Western Digital Black SN850X, Crucial T500, or Kingston Fury Renegade, this drive gets absolutely smoked on raw speed. Those are NVMe drives pushing thousands of MB/s, while the 860 QVO is stuck at 550 MB/s. But that's not really a fair fight. The more relevant comparison is Samsung's own 860 EVO, which offers 600 TBW endurance and a 5-year warranty for roughly the same money. The QVO's only real advantage is capacity per dollar when it's discounted. Against other SATA drives, it holds its own on sequential performance but falls behind on endurance.

Pricing is where this gets tricky. The drive lists between $250 and $259 across two US listings, which is steep for a 1TB SATA SSD in today's market. Affordability ranks at just 41st percentile in our database. The original pitch was that QLC would make terabyte-class SSDs cheaper, but at this price point you're paying a Samsung brand premium. If you can find it on sale, it's a reasonable buy. At full price, you're better off looking at TLC alternatives or even entry-level NVMe drives.

The Samsung 860 QVO is a 1TB SATA III drive that tops out at 550 MB/s read and 520 MB/s write. That's about as fast as SATA gets, but it's also the ceiling for this form factor. The real story here is the QLC NAND, which keeps costs down but drops endurance to 360 TBW, well below the 600 TBW you'd get from Samsung's own TLC-based 860 EVO.

Our database puts this drive's social proof in the 95th percentile, which means owners really like it. User sentiment lands at 79th percentile with a 4.8-star average across nearly 15,000 reviews. But speed sits at just 34th percentile overall, because we're comparing against NVMe drives that run circles around SATA. For a budget SATA upgrade, though, this thing is solid.

Skip this if you have an M.2 slot available. NVMe drives like the WD Black SN850X or Crucial T500 cost similar money and deliver dramatically better performance. Also skip it if endurance matters to you. The 360 TBW rating is half what the 860 EVO offers, and the 3-year warranty is two years shorter. If you're doing heavy video editing, constant large file transfers, or running a database, QLC NAND will slow down under sustained writes and wear out faster. At $250+, you're paying too much for a drive that's outclassed by cheaper TLC options.

The 860 QVO is a perfectly fine SATA SSD that's been somewhat left behind by the market. Owners love it, with a 4.8-star average and sentiment in the 79th percentile. But the 360 TBW endurance and 3-year warranty are real compromises compared to TLC drives, and the $250+ asking price makes it hard to recommend at full retail. If you're upgrading an older laptop or desktop that only has SATA ports, and you find this on sale, it's a solid pick. Otherwise, save your money or look at NVMe.
