Nope, that no longer computes, Brandon, not when you're using much the same argument (plus memory's cheap prices) to overpurchase RAM. I'm buying a gig of RAM, which is probably 4 times what I really need (even being liberal about it), so doubling the disk, when future expansion is already factored in, it makes no sense. I run a scsi system, where disk is dearer than IDE disks, and that's another consideration (which I didn't tell you about, I like to win my arguments unfairly, don't I?) I just bought that new Fujitsu Ultra160 screamer, fastest disk in the West (3.5ms access, 15K rotation). Eat my dust! > > Brandon D.
