Good enough to capture 640x480 AVI @ 30fps. scsi drives are always more expensive so unless you are running a real server I'd just stick with IDE. IDE drives are just incredibly inexpensive these days (at least in the US). dman> Does RAID restrict the combination of disks I can have?

You partition them and start RAID partitions. So it should be no problem to use different disks. From an efficiency point of view you want the disks to be of similar performance. Once again, unless you really need it I wouldn't mess with RAID. Unless of course you just want to because you want to. Brian
