Agreed, in general when comparing throughput in pre-4.3 SCSI Manager macs to the fastest SCSI disks available (which have their own latencies) in my testing, I would need a much larger set of samples to tell if the differences are statistically significant, it's that close. However, when trying to account for bus cycles, understanding the behavior of SCSIManager and latency is important.

And also 100% agreed on CF cards making a huge difference, the single largest difference in the whole setup IMO.
