Typical read and write speeds for consumer drives with spinning platters remain in the 100MBps to 200MBps variety, depending upon platter densities and whether they spin at 5,400 rpm (more common) or 7,200 rpm (less common).

Virtually speaking, this suggests you can move gigabytes of information (say, a 4GB feature-length movie, or a year’s worth of household pictures) to an [dcl=8665] in seconds instead of the minutes it would take with an external spinning drive.
