On a SCSI bus, I can have multiple drives and if I balance the load on the drives then I am able to increase the overall throughput of my disk subsystem up to the theoretical max of 10 MB/s right? Is this true for IDE or E-IDE? E-IDE can achieve bus throughput > 10 MB/s but there are few drives that can sustain such transfers. But if I have two drives on the same IDE adapter and I balance the load across the two drives, will I get the same performance benefit as with multiple SCSI drives? What if I have two drives on two different IDE adapters?
