This thing does what it's supposed to with different interfaces. It runs cooler than my hitachi external 1tb and is decent size. Comparing w/ the previous model line where the light was a circle, the power button is now on the backside.
slim size; runs cool; multiple interfaces
like the previous person said; this thing sometimes disappears from device manager; but I've noticed this in most western digital external harddrives that I've owned in the past 3 years firewire/usb
