I guess this is probably will get some good input. I currently stream from an external HD seagate 500 GB (400 firewire), drive with all my iTunes content, works great, one small problem I have 31GB left on the drive. I am in the marked for a new external HD, I stream to 3 Apple TV's and 4 apple computers, from one iTunes. I have 3 wireless networks so things just zip along (2 N networks one a 5 GHZ, one a 2.4 GHZ, also a G network for everything else). The iTunes server sits on it own N network, and ethernet connected to the other N network. Requirements, I need a reasonable priced 1 TB drive, that runs 24/7? any ideas? Needs to be firewire (800 better, but 400 works just fine), USB cannot handle the traffic. Looking for a drive that does not over heat, or has fans that kick in. in the passed I have had 2 WD die on me, one 1TB studio (has 2 500GB inside), and the other was a 500 GB studio I got from the Apple store, it would get to hot, until one day started to get into trouble running. I have had one seagate 750GB, but the 2 firewire ports are fried, USB still works but struggles streaming content.
