Kunga:

I'm not suggesting you do that with all 3000 discs :-)

I'm providing an exercise to determine where the bottleneck is.

Yes, making an immage takes a long time, but you should also choose the 
"Master" setting with no compression. A further exercise would be to 
benchmark both the compressed and uncompressed versions to see how each 
taxes you CPUs.

Reading from a disk image should give you a peak source of 66MB/s (sustained 
20-30MB, depennding upon the drives capacity), compare to the reader's peak 
of 7.8MB/s and sustained average of ~5.4MB/s.

It should also speed things if your source and destination drives were 
different (not just different partitions), and higher-capacity drives 
typically have higher sustained throughput.
