Pros: No connection issues others speak of (after updating to latest firmware)
Solid transfer speeds ~140mb/s
Nice looking

Cons: The box feels pretty cheap being made entirely of plastic. The top half that lifts off to insert the drives sort of shifts around when you move it or hold it even when it's attached. The back right edge is all chewed up, looks like a cat gnawed on it. Just overall poor quality for the price, at least in terms of physical design.

Pros: Aesthetics
Capacity

Cons: The tip of the metal enclosure is so thin it's already dented inward after a few weeks
Slow write speed

Other Thoughts: I really liked it when I first received it and could forgive the slow write speed, it's intended as a backup to read from more than anything, but the metal casing (specifically at the tip where you insert it) is too thin to hold up over time. Needs a cap or thicker material.
