These conventional arduous drives have largely fallen out of favor to be used as system drives, however their bigger capacities and less expensive per-gigabyte value means they’re nonetheless a highly regarded selection for exterior storage use.
In recent times we now have witnessed the solid-state drive revolution. These drives are principally a sort of flash reminiscence, the place information is written onto chips reasonably than magnetic platters — which means no shifting elements, which in flip means quicker learn/write speeds in addition to (in principle) elevated long-term reliability.

Remember to double-check this and keep away from any that use the older 5,400rpm commonplace, though these are much less widespread now. Strong-state drives naturally provide the very best learn/write speeds, however, as defined above, provide the least worth per gigabyte.
