I make a list of priorities and then act on them. Having heard yours, I like the direction you are heading.The Netgear ReadyNAS is a solid product. It hits your hot buttons...good dumbyproof array preformance and has great capability for easy back up routines. Remember...an array increases as you add drives because they hit all drives at the same time and while writting or reading; thus it's best to get the 4x250gb box. The ReadyNAS is packaged with decent backup utilities and comes with a USB port. What my guys set up at my freinds house...(because he lost some of his family digi photos once)...is the ReadyNAS and then we hung an external WD Hardrive and it copies all data to the external everynight. Now if you really want extra security for your data...(in case of home fire ect.)...buy two cheap external hard drives and keep one at the office, then rotate them every week or two.
Good luck with your project and happy listening.
