    Great read/write speeds as long as you are utilizing usb 3.0 . Does run hot which will add to overall computer heat especially if you are using a Pi. Tight design so fits well with multiple usb devices.

    I was looking for something to relieve my netbook of a lot of stuff, that, apparently, was making it run slow. Then, while browsing the Best Buy Site, I came across this little gadget. Read the reviews; and most sounded very promising. So, I ordered one. No regrets, so far. In fact, thinking of ordering another for my daughter who is at College; I like it so much. P.S. Again, I NEVER recommend anything to anybody; not, even, my children. I just buy whatever, if I like it, and hope that it is liked.

    Works great to back up data. What I don't like is it looks exactly the same with the 64GB one, so I have to put a label on each so I can distinguish them.
