Manufacturer description

This second-generation QVO drive improves performance by 15 percent over the previous model, which shows up most clearly in sustained everyday workloads like game library loads, photo and video archives, and general application launches. The standard 2.5-inch SATA III form factor drops straight into desktop drive bays and most laptops without an M.2 slot, making the 870 QVO a practical way to retire a mechanical hard drive or add bulk flash storage to an older machine. Capacity options run all the way up to 8 TB, so you can consolidate a sprawling media or Steam library onto a single drive…

Frequently Asked Questions

Is the Samsung 870 QVO fast enough to replace a hard drive?

Yes. It is a SATA III SSD with 15% improved performance over the previous QVO generation, so boot, game load, and file access times drop dramatically versus a mechanical drive.

What capacities does the 870 QVO come in?

The 870 QVO line is available in capacities up to 8 TB. The MZ-77Q1T0BW model number refers to the 1 TB version; confirm the exact capacity on the listing before ordering.

Will this SSD fit in my laptop?

It uses the standard 2.5-inch SATA III form factor, so it fits any laptop or desktop with a 2.5-inch drive bay and a SATA connection. It will not fit an M.2-only system.

What warranty does Samsung offer on the 870 QVO?

Samsung includes a 3-year warranty on the 870 QVO. Check the product listing for current terms and regional coverage details.

What kind of memory does the 870 QVO use?

It uses Samsung V-NAND 4-bit MLC, the second generation of the QVO range's QLC technology, which prioritizes capacity per dollar over the peak write endurance of TLC drives.
