I just purchased a new ASUS P5AD2-E Premium motherboard and I'm about to connect my hardrives. I have a new Maxtor Diamondmax 10 160GB SATA 7200 RPM drive and a Quantum U160 SCSI 10k RPM drive. Which should I go with? I'm assuming the SCSI will be faster, but will it be much faster? Since, using SCSI will take some work off the CPU...is it worth it? will I notice much performance difference?
