"....and.....should I get a a Hd with a dock?"
This might be a very usable solution, IF...
- You don't need "portability" that a "drive in an enclosure" makes easy
- You don't need to have the external storage powered-on continuously.
I have a USB/SATA dock and it's one of the most useful "storage tools" I have.
It's easy to swap out drives as needed.
For example, you might keep a "dedicated drive" for ProTools, and another for backups, and then just "swap them" as needed.
If you decide to go this route, I would suggest that you also consider the Other World Computing "Voyager" which has not only USB but Firewire 800/400 as well. The higher speeds would help out with ProTools and audio files. I've seen a good buy on the Voyager units here:

(no financial interest)
The drawbacks to the "dock" scenario are:
- Not as easily portable (but can indeed be carried around)
- May not be best suited to periods of "extended use" as they don't have forced-air cooling (I have kept mine running with a drive for a few hours' at a time without problems).
Again, these can be VERY handy items to have around, particularly if you have several drives to manage.
