I have several 2TB external hard disks for backups and storage.
These of course are slow; I have USB 2 at the moment.
***Is it possible to convert or instal USB 3 into my computer?
***I've read the speed increase over USB 2 isn't as great as promoters imply. The PC has an eSATA external connection (and there's firewire). What's my best bet for connecting to an external hard disk?
Or should I stick with USB 2 and rish the disks overheating as they can take a day or two to fill up.

To avoid confusion: can someone tell me if a PC (quite high spec a few years ago) quad core etc with ASUS P5NE-SLI motherboard can power USB 3? This would ease my backup time problem (I think - it may be the speed increase is not as great as claimed)
So 2 questions-
 Can my PC be unpgraded to USB 3
 Is USB 3 in fact as fast as is claimed, or would i be disappointed in file transfer times? I have quite a lot of informative websites, which are grabbed, a lot of data.
