What NAS product or combination of NAS products would best suit the following home network requirements: RAID 1 storage for important media, eg. photos, home video, etc with minimum capacity of 500GB.

Use RAID 1 for all of the data on the NAS and then burn all your valueable stuff (photos, wedding video etc) to optical of some description.

Personally I have a QNAP 209 with two 1TB drives, mirrored and then a seperate 1TB USB drive for a seperate backup (to protect against catastrophic failure of the QNAP). Good thing being that the QNAP has a one touch backup to USB drives so anytime I make a significant update to my video library I reconnect the USB drive and hit the backup button
