I'm looking to purchase a NAS device. I have been looking at the Seagate BlackArmor NAS 220 (Raid1). I'm looking to store my iPhoto album on this external along with my iTunes music and movies. I also wanted to use Time Machine over WiFi. I also want to be able to connect my XBOX 360 for streaming movies/music/pictures to my living room as well as my AppleTV in my bedroom. I was planning to use 1 of the 2 USB ports for my Printer and the Second USB port for an additional 500GB drive to backup my Photos incase both drives fail with raid1. Anyone using the Seagate BlackArmor NAS? or would you recommend another NAS device?
