Normal read and write speeds for consumer drives with spinning plates remain in the 100MBps to 200MBps variety, depending on plate densities and whether they spin at 5,400 rpm (more common) or 7,200 rpm (less common).
Virtually speaking, this indicates you can move gigabytes of data (state, a 4GB feature film, or a year’s worth of household images) to an - in seconds instead of the minutes it would take with an external spinning drive. Not only is it much faster to check out and write data saved in flash cells, however it’s likewise much safer.

5-inchers). Their total storage capabilities are limited only by their variety of available bays and the capabilities of the drives you put in them.
