Firstly, Mezzmo is an awesome product. Love it!

I recently had a hard drive failure, and I'm now looking at the most cost efficient manner to introduce a) redundancy and b) more storage capacity to my network.

My first thought was a NAS to store all of the files, and a reasonably beefy computer (I have a 3.2ghz Phenom II x4 /w 8GB of RAM that currently does the transcoding quite comfortably) to stream across the network (gigabit ethernet, all around the home). Would it be reasonable to assume that if the NAS was setup with RAID 5 and dual gigabit that it would provide sufficient throughput while streaming to the Transcoding computer?

Do any other Mezzmo users have any experience using a NAS in this fashion? I'm considering a QNAP or a Netgear ReadyNAS as they seem to receive quite favourable reviews all around.
