I was looking at the xSeries boxes, and there (if I'm reading the specs correctly), you can only get hot swap on drives of 146GB or more. Since RAID5 requires three drives, that means I'd end up with 300GB of storage at an additional $2100 for the machine (as opposed to 73GB using the smaller 36GB drives). I don't need that much storage. Joe
