Thecus, N5200 NAS is for the people with actual secure storage needs. The N5200 houses five hard drives, with which on an average count, can get you about 3.75TB worth of 750GB drives in this thing. For networking there are four Gigabit Ethernet ports. On the back, there is now an eSATA port for expandability, so 5 drive bays is not a hard limit. It also has 4 GigE ports, up from the two 10/100s found on the older model. The box runs on a Celeron M CPU to manage all the crazy storage and bandwidth, and supports USB RAID if you’d like to get all redundant on your flash drives. Thecus has added AFP and NFS network support — along with the usual suspects — and are even throwing in an admin utility for Macs. Overall, the device is quite feature full, and its RAID6 and RAID10 support make it a haven of redundancy.
