This is not a good way to create ISO images from CDs, as dd(1) provides no error checking when creating the image. Instead, you should be using:

I always add something like bs=1M for performance. At least once I dumped a harddrive with the default block size and the performance was awful. Can anyone verify the performance difference in this case?

If your block size matches the block size of your block device, then you will maximize performance with dd(1). Again though, dd(1) is not the tool for this job, and readom(1) will read the optical media as fast as possible, while maintaining the checksums.
