Update: Worked for a few weeks and then crashed. BAD product! --------- ------------------- I have a fresh clone on a USB 2 external drive but it is very slow because it is USB 2 is can take up to an hour. I was able to cut my time down to 10 minutes with this great adapter! Of course, I didn't have to create a new clone from scratch, but just the file comparison that Carbon Copy Cloner does (on a Mac) can take up to 15 minutes. I can't tell how it will work on Windows, but I suspect it's pretty much the same. All in all a solid purchase!
