I bought one of those - interesting concept until the two of the Seagate 400GB SATA drives decided to die - one on its own and one as the RAID5 array was rebuilding - hang on, I can hear the phones ringing off the wall at Kroll Ontrack - cost us about £8k for OnTrack to recover the data (was worth it and it a brilliant service).

I decided that I didn't like the ReadyNAS, so went out and bought a HP NAS which runs Windows Storage Server and has 1.6TB of space. Cost the same as the Infrant/Netgear ReadyNAS and its a lot better and so much easier to use.

Sorry, but its just easier to pay BillG - I haven't got time to experiment with other OSs.
