My Sony VAIO notebook unfortunately has no USB 3.0 ports, but three USB 2.0 ports. The possible speed of the hard disk drive I cannot use with it, but I am planning to buy a new notebook maybe this year.
But anyway saving and loading files or running portable apps e.g. Firefox Portable or Notepad++ is comfortable fast and silent.
After the startup procedure first of all I have copied all data from the older hard disk drives to this new one as a backup. Although this procedure has needed hours cause of my notebook has no faster USB 3.0 but much slower USB 2.0 ports only, it became warm to the touch only. That´s surely by curtesy of the three millimeter thick aluminium casing!
All advantages of this external hard disk drive you will find on the next page ...
