Spire Megapod III is a great looking external HDD enclosure with sleek design and finish. The Power supply is small, which is great when you're on the road. The enclosure gets pretty hot because it uses passive cooling.
Unfortunately, the HDD activity LED is very annoying. The switching between red and blue steals focus, and it would've been better to move the activity LED to the back of the unit. We do miss more sound insulation, perhaps in the form of rubber feet and rubber between the HDD and the drive tray.
It is not possible to stack several enclosures, nor is it possible to use the unit horizontally.
The selling point of this unit will be the retail price, and a very nice design
(iPod / Mac feel).
