Samsung 870 QVO SSD line with QLC memory comes out

As expected, Samsung’s SSD product line has been expanded with the 870 QVO line of 92-layer 3D V-NAND chips with four bits per cell (QLC). The devices are made in a 2.5-inch form factor, equipped with a SATA 6 Gbit/s interface and are offered in versions with capacities from 1 to 8 terabytes.

According to the vendor, 860 QVO novelties differ from those released in 2018 with a 13% increase in random read/write performance. The 870 QVO is based on the Samsung MKX controller with a 1-8GB LPDDR4 buffer.

Sequential read speeds up to 560MB/sec and write speeds up to 530MB/sec, but only within an SLC cache. Outside of it, linear writes will drop to 80 Mbytes per second for the 870 QVO terabyte version or to 160 Mbytes per second for the larger models.

The maximum IOPS is 98,000 read operations and 88,000 write operations. All SSDs are backed by a three-year manufacturer’s warranty and have a stated lifespan of 360 to 2880 terabytes depending on drive capacity.

In terms of price, a Samsung 870 QVO with 1TB, 2TB and 4TB capacity will cost at least $130, $250 and $500 respectively. The 8-terabyte model is scheduled to be released in August and, according to preliminary data, its price will be about $900-1000.
