Keep your scsi happening, for storage use IDE. Yes it's basic but thats the way I have it, an boot from U3.
Nothing bad about raid on IDE, granted, it is fast, quality wise and I'am running out of excuses here.lol.
BTW, you will not out perform scsi as this is the breeding ground for IDE at present, newer drive technology is on the way but as I said its Scsi at the moment for having the latest, and reliability it craps all-over IDE!
This is my opinion and thats set in concrete, well for today anyway.
Anyway I think you have succesfully baited me.lol
