Samsung 860 QVO SSD 4TB

Bottom line: The Samsung 860 QVO SSD 4TB ($589.00 on Amazon as of 2026-10-06): 4TB in a 2.5-inch SATA bay - no M.2 slot or PCIe lane required; main trade-off: SATA caps it at ~550MB/s - an NVMe drive is several times faster.

Pros & Cons

Pros

  • ✓ 4TB in a 2.5-inch SATA bay - no M.2 slot or PCIe lane required
  • ✓ Up to 550MB/s read and 520MB/s write, near the SATA 6 Gb/s ceiling
  • ✓ AES 256-bit hardware encryption with TCG Opal and IEEE 1667 support
  • ✓ Intelligent TurboWrite buffer holds write speed up through long transfers

Cons

  • ✗ SATA caps it at ~550MB/s - an NVMe drive is several times faster
  • ✗ 3-year limited warranty is shorter than the 5 years on Samsung's EVO line
  • ✗ QLC V-NAND means sustained writes slow once the TurboWrite buffer fills
  • ✗ Up to 97,000 random read IOPS trails current NVMe drives by a wide margin

Manufacturer description

Samsung's 860 QVO 4TB brings terabyte-scale storage to any machine with a spare 2.5-inch bay, and it does it on the SATA interface that nearly every desktop, laptop, and NAS already supports. Built on Samsung V-NAND, this drive posts sequential reads of up to 550MB/s and sequential writes of up to 520MB/s, with random reads reaching up to 97,000 IOPS. Samsung's Intelligent TurboWrite feature uses a larger variable buffer to accelerate writes and hold performance steady through long transfers, which matters when you are moving hours of 4K video or a bulk photo library rather than a handful of…

SpecPicks Verdict

SpecPicks scored Samsung 860 QVO SSD 4TB using a rating × review-volume × price-fit model applied to published specs and reviews across the ssds & storage category. Samsung's ssds & storage lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here.

Frequently Asked Questions

How fast is the Samsung 860 QVO 4TB?

Samsung rates it at up to 550MB/s sequential read and 520MB/s sequential write, plus up to 97,000 IOPS random read. That is essentially the ceiling of the SATA 6 Gb/s interface.

Will this SSD work in my older PC or laptop?

Yes, if it has a 2.5-inch drive bay. The interface is SATA 6 Gb/s and it is backward compatible with SATA 3 Gb/s and SATA 1.5 Gb/s controllers, so older systems work at their own slower link speed.

What warranty does the 860 QVO come with?

A 3-year limited warranty from Samsung. Check the product listing for current terms and regional coverage before you buy.

Does the 860 QVO support hardware encryption?

Yes. It includes AES 256-bit hardware-based encryption compliant with TCG Opal and IEEE 1667, so you can secure the drive without a software encryption layer reducing throughput.

Is 4TB enough for a game and media library?

For most users, yes. Samsung positions the 4TB capacity for storing hours of 4K video and thousands of photos, and it comfortably holds dozens of modern 100GB-plus game installs.
