I did think about this when I set the machine up. The issue is that I need the space -- a 146 Gb mirrored pair isn't big enough. If I set them up as separate disks, then if I lose one of them, I'm down anyway, and can't have a filesystem bigger than 146 Gb. So I chose raid 0, which gives me the flexibility of almost 300 Gb of space and maybe a little performance boost when the stars align. I back this system up often, to minimize my vulnerability. At some point, I may replace the drives with the 300 Gb 15k SAS drives that are now available and getting cheaper with 6 Gb/s SAS becoming available. If I do that, I'll arrange them as a mirrored pair. I've got X up, mouse works, backup SATA drive in USB shoebox works, so it looks like I'm ok. The system takes forever to boot, but I can probably fix that with config and ukc (nice feature!). Thanks again for your help. /Don > > Regards, > David
