When compared to the disk transfer rates, 1Mb/sec does not seem to be a lot of data?
Perhaps not. But back when we were deciding on SCSI vs PATA/IDE, it was. Remember that older IDE involved the CPU to a much larger extent than SCSI does. That was one reason SCSI was preferred. SATA seems better in this respect (CPU usage).
I ran some tests a few months ago on larger (1-2-3Tb) drives - on a 3Tb WD Caviar Green, the read/write varies from 120Mb/sec to 58Mb/sec. I did not look at io rates or disk beahviour over longer sustained periods of time though.
Sustained use is a big part of the question. Also, the data is to different files, and thus different locations on the disk.
