Samsung 870 QVO 8 TB SATA 2.5 Inch Internal Solid State Drive (SSD) (MZ-77Q8T0)

Bottom line: The Samsung 870 QVO 8 TB SATA 2.5 Inch Internal Solid State Drive ($1584.45 on Amazon as of 2026-10-06): 8 TB in one 2.5-inch bay, the largest capacity in the SATA SSD class; main trade-off: QLC NAND, not TLC or MLC, so sustained write performance drops on long transfers.

Pros & Cons

Pros

  • ✓ 8 TB in one 2.5-inch bay, the largest capacity in the SATA SSD class
  • ✓ 560/530 MB/s sequential read/write saturates the SATA 6 Gb/s ceiling
  • ✓ Backward compatible with SATA 3 Gb/s and 1.5 Gb/s on older systems
  • ✓ Standard 2.5-inch form factor fits laptop bays without an adapter

Cons

  • ✗ QLC NAND, not TLC or MLC, so sustained write performance drops on long transfers
  • ✗ SATA caps it at 560 MB/s while NVMe drives run several times faster
  • ✗ No M.2 option at this capacity, so it needs a free 2.5-inch bay and cables
  • ✗ Samsung positions it for mainstream PCs, not sustained server or write-heavy workloads

Manufacturer description

The Samsung 870 QVO 8 TB is the largest 2.5-inch SATA SSD Samsung builds, and it exists for one reason: replacing a shelf of mechanical drives with a single silent, shock-resistant volume. Built on Samsung's second-generation QLC NAND, it delivers sequential read and write speeds up to 560/530 MB/s over the SATA 6 Gb/s interface, which saturates what SATA can carry. Your real-world numbers will track your system hardware configuration, but on any desktop or laptop built in the last decade the jump from a spinning 7200 RPM disk is immediate in boot time, level loads, and project file opens…

Frequently Asked Questions

How fast is the Samsung 870 QVO 8 TB?

Samsung rates it at up to 560 MB/s sequential read and 530 MB/s sequential write. Those are SATA 6 Gb/s interface limits, and actual speeds vary based on your system hardware configuration.

Will the 870 QVO work in my older PC or laptop?

Yes. It uses the SATA 6 Gb/s interface and is backward compatible with SATA 3 Gb/s and SATA 1.5 Gb/s, so it runs on older controllers at that port's speed. It is a standard 2.5-inch drive.

Is QLC NAND a problem for gaming and everyday use?

Samsung designed the 870 QVO for mainstream PCs and laptops in personal, gaming, and business use. QLC trades sustained write endurance for capacity, so it suits read-heavy libraries better than constant large writes.

Is 8 TB really the largest capacity available?

8 TB is the top capacity in the 870 QVO line, and Samsung describes it as the largest of its kind in the 2.5-inch QLC SSD market. Lower capacities in the same family are also sold.

What warranty does the 870 QVO come with?

Warranty terms are not listed in this product's specifications. Check the current Amazon listing or Samsung's official support page for the warranty period and endurance rating that apply to the 8 TB model.
