I'm thinking about putting a 15K SCSI drive on my 1GHz Powermac. I am going to use the SCSI disk for a system/applications drive and use my ATA drives to store miscellaneous data. From the data I have read, I should see a huge increase in throughput. Comments? I am looking at the Adaptec 29320 controller and the Seagate Cheetah drive. Is the 29320 compatable with the Quicksilver Powermacs? On the other hand, I could take the money and put it into the next generation Powermac. What to do?..... Thanks in advance.
