Earlier this year Samsung released its 870 QVO SATA SSD. This SSD is composed of its second- generation quad-level cell (QLC) flash technology. We have already reviewed the 1TB and 4TB models of the drive. One of the big benefits of QLC is that it is less expensive than TLC and you can get higher capacities to replace legacy HDD. That is what we are looking at today in the 8TB.
