I've been using pathrate, pathload, (dbench/tiobench - don't remember if these compiled on Mac) and various built-in tools and wanted to know what others used and good/bad points.

I don't know of any single app or utility that I would suggest to
test/monitor Disk I/O.  The one utility that I do use frequently to
monitor disk I/O and other activity is iostat (8).  I believe this is
available on Darwin, on Gnu/Linux i believe it's called sysstat.  As far
as RAID caching perf. I have found that this varies from hardware vendor
to hardware vendor.  If you are using the Apple XRaid's I believe there
are options in it's management package to check this out.  I have used
similar, vendor specific, software to monitor IBM JBOD's and RAID's as 
well as SGI RAID's.
