I have purchased 2 such drives and I have to say, overall I am a bit unhappy. Yes, the size is great when speaking of 64gb/128gb of storage. I don't notice any performance lag, but I am definitely not a heavy user. What I am most disappointed with is that the Storedge does not fit flush to the body of the MB. Why is this such a big thing for me? I have now damaged 2 Storedge cards when either placing them into my Swiss backpack or when the edge bumped into something. So far this has not caused the second disk to fail, but I am assuming that is just a after of time. So, be careful how you place your computer into a backpack or definitely don't let it slide off a car seat into the door. The kip that I have seen referenced is more than just a little for the nail to grab. It's a good 1/4"+ on my 2013 MBP. Maybe something is wrong with my machine...
Hope this helps,
Richard
