I have worked with at least four major name brands of scsi and ide raid
controllers and so far the one I have found to be generally the most
featured and fastest is the ICP Vortex controllers
(http://www.icp-vortex.com/). It is also more expensive than the others
but has been worth the cost IMHO. It has a command line utility to
measure disk performance and I believe the source code for it is
available. I have measured over 200 MB/s reads off these controllers on
3u disk array units. I'm sure I could have gotten more with additional
tuning.
