I’ve been mostly using a 9600 running 9.2.2 for a few older games. Quite often when it came to a save or a reload, I’d have an annoying wait while the drive spun up.
I had a generic ATA to CF adapter kicking around so I thought I’d see about using it. I tried connecting it as a second drive on the PC133 card but the system would freeze during bootup. Didn’t have any luck adding it to any of the SCSI to ATA adapters I have. Either it'd freeze or wouldn't be recognized. I had some PC100 cards so I put the adapter on it’s own card and it worked like a charm. Copied the whole boot drive over to it. It was a little faster booting than the 80gb on the pc133 card but not hugely. Still, no extra noise and no spin up time.
