Curious to know if there is a good currently available Thunderbolt single drive external storage solution available.

I have a large sized SSD, and a 2TB HDD that I'd like in separate enclosures. One for backup/time machine and another to store more recent backups, and all my programs and a few movies etc.

What would you guys suggest? I don't mind spending a bit of money, but keep in mind I'd at least like to make use of the Intel 520 SSD I have. There's got to be something out there...
