According to Samsung, the combination of the QLC NAND and its own MJX controller should bring the same level of performance as 3-bit MLC-based SSDs but at an affordable price point. Bear in mind that this is the first QLC-based 2.5-inch SATA SSD series. 

The Samsung 860 QVO SSD lineup launches in 1TB, 2TB, and 4TB capacity options and will offer sequential read and write performance of up to 550MB/s and 520MB/s. The random 4K read and write performance peaks at 97K IOPS and 89K IOPS.

The Samsung 860 QVO SSD lineup uses TurboWrite technology, featuring write buffer that should provide a significant performance boost in write performance. According to Samsung, it peaks at 42GB for the 1TB model and 78GB for 2TB and 4TB models.

The endurance is rated at 360TB, 720TB, 1440TB for 1TB, 2TB and 4TB models, and it is backed by a three year warranty.

According to Samsung, the suggested retail price is $149.99 for the 1TB model, $299.99 for the 2TB, and $599.99 for the 4TB model. These prices put the Samsung 860 QVO SSD series at around 15c/GB, a somewhat lower price compared to high-capacity TLC drives. The Samsung 860 QVO 1TB model should be available in mid-December while other two higher capacity models will be coming at a later date.
