It heavily depends on the server type. For a typical, even heavy loaded
webserver it makes much sense as disk I/O is no issue there. For loaded
mailservers a seperate _very_ fast disk (15k RPM SCSI) for the queue makes
really sense. If you have more than one disk and disk I/O is an issue SCSI
makes sense, otherwise not.
You may wan't to have a look at http://misc.bsws.de/obsdtuning/webserver.txt.

Unix is very simple, but it takes a genius to understand the simplicity.
