Summary: Been using this with SuperDuper to make a cloned backup of my Mac for a couple of years now. So mostly, it just sits in a fire safe until the next time I make a new backup, every couple of months. But for this simple task, its been flawless. Very nice design. No external power supply needed.
Summary: These are great portable 1tb drives for transporting data - my wife uses one to back up her Mac laptop and I keep one on line to park data I might want to use at another location - so far, totally reliable and a decent price for what you get
