I currently have a MOBO that supports 4 sata drives. I also use an esata raid array and a NAS box which is raid too. This is all about paranoia and backing up various drives.
After a recent HD failure, I'd not like to find a mobo that will service 8 drives but individual ones not in RAID arrays. The reason is because it took ages to download my Mozy back ups so I'd like stuf locally stored too.
I already have a cecent dual core AMD2+ processor and 4GB of dual channel so its just the board I'm after. Oh it shoudl also have as many usb ports as poss too!
