Samsung 1TB SSD

The 860 QVO 1TB hits 550 MB/s read and 520 MB/s write, which maxes out SATA III but lands in the bottom third for speed in our database. The 4.8-star average from 14,867 reviews shows buyers love it as an HDD upgrade, but the 360 TBW endurance and 3-year warranty are clear downgrades from the 860 EVO. At $250+ USD, it's overpriced for what you get unless you're stuck with a SATA-only system.

Let's be honest about what this drive is. The 550 MB/s read and 520 MB/s write are SATA ceiling numbers, and the 96K random read IOPS and 89K random write IOPS put it in the 44th percentile for random performance. That's middle of the pack, and in a world where NVMe drives hit 7,000 MB/s, these numbers look ancient. But context matters. If you're coming from a mechanical hard drive that struggles to hit 120 MB/s, you're looking at a 4x to 5x improvement in real-world responsiveness. Boot times drop, games load faster, and Windows stops feeling like it's wading through molasses.

The QLC NAND is the trade-off. Samsung's Intelligent TurboWrite uses a variable SLC buffer to keep write speeds high during bursts, which helps mask the slower native QLC write performance. The DRAM cache also keeps things snappy for everyday tasks. But sustained writes, like moving a 200GB game library, will eventually drop below the advertised numbers once that buffer fills. For a drive that's mostly reading games and loading apps, you'll rarely notice. For heavy video editing or constant large file transfers, you will.

Stacked against the competition in our database, the 860 QVO looks like a relic. The Western Digital WD_BLACK SN850P and SanDisk Black SN850X are PCIe 4.0 NVMe drives that hit 7,000 MB/s reads, roughly 12x faster than this drive's 550 MB/s. The Crucial T710 and Lexar NM1090 PRO push even further into PCIe 5.0 territory. Even the Kingston Fury Renegade SFYRDK/2000G doubles the capacity at 2TB while leaving the QVO in the dust on speed. The only place the 860 QVO wins is compatibility. If your machine has a SATA port and no M.2 slot, none of those NVMe drives will fit. That's the real market for this drive, people with older systems who want a big speed boost without a full platform upgrade. For anyone with an M.2 slot available, there's no reason to buy this over an NVMe drive at these prices.

Pricing is weird right now. US listings run $250 to $259, which is honestly too much for a SATA QLC drive in 2025. You can find NVMe drives with 5x the speed for less money. The Japanese listing at 38,000 JPY and the Mexican listing at 9,070 MXN tell a similar story, this drive is priced like a premium product but delivers budget-tier performance by today's standards. The value proposition made sense in 2018 when QLC was the cheap way to get 1TB. Now it's a hard sell unless you specifically need a 2.5-inch SATA drive for an older laptop or desktop without M.2 slots. Buyers in the reviews consistently call it a great value, but that sentiment is frozen in time. At current prices, you're paying a Samsung brand tax on aging hardware.

The Samsung 860 QVO 1TB is a SATA III drive that tops out at 550 MB/s sequential read and 520 MB/s write. That puts it in the bottom third for speed in our database, which sounds rough until you remember this is a QLC value drive from 2018. It was never meant to chase NVMe numbers. What it does offer is 1TB of Samsung V-NAND with a DRAM cache and hardware encryption, and buyers clearly love it. A 4.8-star average across nearly 15,000 reviews puts it in the 95th percentile for social proof, which is basically the crowd screaming "this thing just works."

The endurance story is more mixed. You get 360 TBW and a 3-year warranty, which lands at the 69th percentile for endurance. That's fine for a boot drive or game library, but it's noticeably less than the 600 TBW on the older 860 EVO. If you write a ton of data every day, this isn't your drive. For everyone else upgrading from a spinning hard drive, the jump is massive and the price per gigabyte is still reasonable for a Samsung-branded SSD.

Skip this drive if you have an M.2 slot available. The 34th percentile speed ranking means you're leaving massive performance on the table compared to any modern NVMe drive, and the $250+ US pricing makes that trade-off even worse. Also skip it if you do heavy sustained writes, video editing, large file transfers, or constant database work. The QLC NAND and 360 TBW endurance will bottleneck you, and the 3-year warranty offers less peace of mind than the 5-year coverage on TLC alternatives. If you're building a new system or upgrading anything from the last five years, this drive makes no sense. It's a compatibility play for old hardware, not a performance upgrade for modern machines.

The Samsung 860 QVO 1TB is a good drive trapped in a bad price bracket. The hardware is solid for what it is, a SATA III QLC drive with a DRAM cache, hardware encryption, and Samsung's proven V-NAND. The 4.8-star rating from nearly 15,000 buyers tells you it delivers on its promises. But the 360 TBW endurance and 3-year warranty are clear downgrades from the 860 EVO, and the current $250+ US pricing is hard to justify when faster NVMe drives cost less. If you find this drive used or on a deep discount, and you're upgrading an older SATA-only system, it's a perfectly fine choice. At full retail, you're paying too much for too little.
