The iozone benchmark are very interesting (at least for me). A 3 disk R5
setup (with two usable disks) set up with a correct stripe/fs block size
is about 4 times faster than a 4 disk R5 (3 usable disks) setup.
You can find the benchmarks here:

Filesize is 36K so i chose not to send to the list in favour of modem
users. :)
When exams are over i'll try to polish up all the data with openoffice
and make some nice graphs and a html page.
So far i can't wait until my disks are shipped so i can test a 5 disk (4
usable disks) setup.
