Today we test one, yes it will be more expensive as a normal HDD enclosure yet much cheaper than a NAS device, the unit we look at today for example is aesthetically very pleasing, can hold four high performance drives in hot-swappable drive bays, it is really fast, energy efficient, silent and comes with a plethora of connectivity towards your PC, like eSATA, USB, FireWire (400/800), of and I'd almost forget it .. is RAID 0|1|5 compatible.
