Yea, it is a great paper. It is an HTML version of the SCSI PDF I
mentioned a few weeks ago:
http://www.seagate.com/content/docs/pdf/whitepaper/D2c_More_than_Interface_ATA_vs_SCSI_042003.pdf
Someone had mentioned it on the lists a few months ago but I only read
it recently and resuggested it. One problem with the web version is
that the images didn't transfer very clearly. I mention it in my
hardware performance tuning paper.
