Since SCSI only goes to 144G. So I'd end up with 8 disks at least. Then I'd put in on a RAID controller and fiber. But that is way too professional. I'd do that for data-centres etc... SCSI disk have a better MBTF, but MBTF/$$ is something different. No, I'm more looking at 5*ATA 250 Gb at RAID-5, with a few spare disks on the shelf get a good ventilated case. it would be just manageble. --WjW
