Samsung 860 QVO SSD adopts the traditional 2.5-inch disc specification. The internal is Samsung’s independent MJX Controller, Samsung’s self-produced V-NAND QLC flash granules, the capacity starts directly at 1TB, and there are 2TB, 4TB, respectively equipped with 1GB, 2GB, 4GB LPDDR4 cache…

The performance is limited by the SATA 6Gbps standard. The continuous read and write is up to 550MB/s, 520MB/ s, and the random read and write is up to 97000 IOPS and 89,000 IOPS.

QLC’s reliability and longevity have caused many people to worry about it. The indicators given by Samsung 860 QVO are really not high: 1TB, 2TB, 4TB lifetime writes are 360TB, 720TB, 1440TB, providing a three-year warranty, which is almost the same. Write once every three days.

But on the other hand, the capacity of these QLC SSDs is large enough, 1TB writes 0.3 times a day, which is equivalent to 256GB 1.2 times a day, which is more than enough for 99% of ordinary users.

More importantly, the price is really low. The official suggested retail price of 860 QVO 1TB is 149.99 US dollars. While the 2TB variant will cost $299.99 and 4TB is available at $599.99


Also according to Samsung’s previously public news, its QLC flash SSD will also have 980 QVO series, adopt M.2 specifications and support NVMe. However, Samsung has not announced an M.2 version of the 860 QVO, yet too.
