Samsung finally has an 8TB solid-state drive that’s ready for the mainstream. The company has unveiled an 870 QVO range of SSDs that ranges from ‘just’ 1TB through to the flagship 8TB capacity — enough that you may not have to worry about free space for a long time. It’s an SATA drive limited to peak sequential read and write speeds of 560MB/s and 530MB/s respectively, but Samsung is promising a 13 percent boost in random read speeds over the 860 QVO.
