Pros: This is in response to the previous review. I suggest you go to the anandtech website for a review. He said that the case was very hard to get into and hard to put back together. Drive got positive review, however. Review dated 8/1/12
Cons: see above. This "review" is a caveat which may be of interest to others considering this or the 1TB version.
Summary: I bought this with the intention of possibly changing out the hard drive with a SSD later or a larger one. Seems like it will be rather easy to open at this point. My only thought is that it would have been much nicer if they would have gone aluminum for the whole thing or a better plastic on top.
Pros: Very inexpensive for a thunderbolt drive. I also like that it is completely powered off the one cable. Speed seems to be much better than my USB portable hard drive that I paid more for last year. Also a big plus is that it comes with a thunderbolt cable which can cost around 50.00 on it's own.
Cons: So far I only have one con. The case while its aluminum on the bottom still feels very cheaply put together. The white plastic top feels kinda thin and I feel like I have to be more careful with it than other portable hard drives I have owned.
