I have had several 7600 they are great systems if today used for text and the occaisional graphic. I now have beige G3 300 and would wish the 7600 back. Now to the topic. I had an ultra SCSI card and H/D in the 7600 because it was cheap and I needed another drive. I swapped them into the G3 which has stanard, ATA drives. Testing disclosed that the ultra was 10 times faster than the ATA, and in the old 7600system was 5 times faster than the standard SCSI. SCSI is now quite cheap, is fast and people wanting fast cheap H/D can't go past ultra wide. my 2 cents fluff
