Lately now we have witnessed the solid-state drive revolution. These drives are principally a kind of flash reminiscence, the place knowledge is written onto chips slightly than magnetic platters — which means no transferring components, which in flip means quicker learn/write speeds in addition to (in concept) elevated long-term reliability.
