Hi There Whit.
Excuse the tired old "What about the disk access" question, but what about the disk access?
In my presennt life I have "downgraded" from a one of those fast 1.3 ghz pentiums to a 1 ghz with scsi (yes laughable for cad, but it works). The "new" machine ripped the old one to shreads. I know there is more to it, but I think disk access is probably one of the most neglected features when we consider speed.
There are cheaply avaialble RAID striping controllers. Hard drive cards that have 128 meg memory capability. 1500 Rpm scsi drives and the like.
I can't understand why we all get preoccupied with Video/Processor/RAM and almost never consider the slowest component (after the human of course) - the disk drive.
If you could double your disk throughput, this could help. I know that in a former life I had a cached controller card that gave me an easy 300 percent improvement (OK it was "tossing" mail on a vesa local bus machine, but I did take a 70 second operation down to about 20 seconds that's a real improvement - I'm a believer).
Next time I have a spare 500 bucks for cad stuff, striped disks here I come . . .
Thanks for listening to the madman.
