I picked this up with a Freeagent GO drive when Amazon recently had both on sale. I have 3 Freeagent GO drives, and 3 different cases!
The first case is the one included with the dock - Nice and simple, but not very much protection. Very thin, but doesn't hold any cables. Should be included with the drive, not the dock.
The second case is the
Caselogic THS-101 Portable Hard Drive Case (Black Houndstooth) - a very nice case (stylish, protection, extra space to hold cables, and feels nice).
Finally, I purchased this case - the VHS-101.
The VHS-101 is very similar to the THS-101, except it has a plain black design (opposed to black-on-black houndstooth). The feel is quite "rough" compared to the soft feel of the THS. Aside from that, they seem to be the same in terms of protection/size. The included pocket is nice, without adding too much extra bulk. Someone mentioned in another review that this space is big enough to hold a 2nd Freeagent drive, and I considered that a selling point (being able to carry 2 drives in 1 case -- awesome!). Unfortunately, it's such a tight fit that I wouldn't trust it - it also doesn't protect the whole drive (the top is exposed about 1").
The VHS has a blue colored inside (the THS has a tan color). I actually found the blue to be very ugly - I don't understand why they didn't just use black? I do like that the VHS uses a metal zipper with a hole on the end (the hole is good if you need to "lock" the case closed with a lock). The THS has a fabric zipper without a hole.
Overall, the case is good in terms of protection/size. It's not stylish like the THS, but it's not super ugly (well, the outside at least!). I don't care for the feel of the case very much, but again it could be work. If you're looking for a portable hard drive case (portable meaning 2.5" USB drive), this is about the best case out there (and believe me, I've looked). With that said, the very similar (but much nicer) THS-101 case gets the top choice. Spend a couple bucks more, you'll probably be happy you did!
