SAMSUNG 870 QVO SATA III SSD 8TB 2.5" Internal Solid State Drive (MZ-77Q8T0B)

Bottom line: The SAMSUNG 870 QVO SATA III SSD 8TB 2.5" Internal Solid State Drive ($1,459.99 on Amazon as of 2026-10-31 02:15 UTC): 8TB in a single 2.5-inch 7mm bay - largest capacity in Samsung's SATA QVO line; main trade-off: QLC NAND, so sustained large writes slow once the SLC cache fills.

Pros & Cons

Pros

  • ✓ 8TB in a single 2.5-inch 7mm bay - largest capacity in Samsung's SATA QVO line
  • ✓ 560/530 MB/s sequential read/write saturates the SATA III interface
  • ✓ 2,880 TBW endurance rating on the 8TB model via refined ECC algorithm
  • ✓ Backward compatible with older 3 Gbps and 1.5 Gbps SATA ports

Cons

  • ✗ QLC NAND, so sustained large writes slow once the SLC cache fills
  • ✗ SATA III caps it far below NVMe drives that hit multiple GB/s
  • ✗ Highest cost-per-drive tier in the QVO family at 8TB
  • ✗ 2.5-inch form factor needs a drive bay and cable, not an M.2 slot

Manufacturer description

The Samsung 870 QVO 8TB is the top of Samsung's second-generation QLC SATA lineup, and it exists for one reason: putting the largest possible single 2.5-inch drive into a desktop or laptop bay. Sequential read/write reaches up to 560/530 MB/s, which saturates the SATA III interface, and Samsung rates accelerated read performance up to 13 percent faster than the older 860 QVO. Endurance on the 8TB model is rated at 2,880 TBW using a refined ECC algorithm, so sustained daily writes from photo libraries, video projects, or game installs are well within spec. The standard 7mm 2.5-inch form…

Frequently Asked Questions

How fast is the Samsung 870 QVO 8TB?

Samsung rates it at up to 560 MB/s sequential read and 530 MB/s sequential write, which is the practical ceiling of the SATA III interface.

How long will the 8TB 870 QVO last?

The 8TB model is rated for 2,880 TBW (terabytes written), using a refined ECC algorithm for stable sustained performance.

Will it work in an older PC or laptop?

Yes. It is a standard 2.5-inch 7mm drive and is compatible with SATA 3 Gbps and 1.5 Gbps interfaces in addition to SATA III 6 Gbps.

Is QLC NAND a problem for everyday use?

For everyday computing, no - Samsung positions the 870 QVO's endurance as equivalent to 3-bit MLC SSDs. Heavy sustained write workloads are better served by TLC or NVMe drives.

What other capacities does the 870 QVO come in?

The 870 QVO line is available in 1TB, 2TB, 4TB, and 8TB. Check the product listing for current warranty terms and stock.
