HEXUS.net has a review of a NAS solution capable of storing in excess of 1TB of data, depending on the hard drives you decide to use, and with RAID 5 protection! From the review: If you're looking for a new means of storing and protecting the vast amount of data you have somehow managed to acquire, then ask yourself whether an IP storage solution would be feasible for you. If you really need a 100% uptime, network attached storage device with access control and hotswap array rebuilds, and you don't mind the 7 hour RAID 5 build (which is only likely to be an issue once,) then the N4100 is worth considering. Just bear in mind that 900GB of protected network attached storage in a sexy black box will set you back a grand.
