I have read of some expectations of raid performance not being
realized by some, mainly raid 0, so here is a thread.
Todays faster drives do not show much performance increase at default
64kb stripe sizes. Manually set the stripe to 32kb or smaller (ami
controller currently cant be set any smaller, the promise can, but
try 32kb as a starting point.
DMA is auto selected in the ami bios, check for DMA settings with
other cards.
Enable the write cache in the ami bios.
Format your file system to a value smaller than the default 64 in
windows fat 32. I used partition magic to do this after a regular fat
32 installation and it made it easier to go back and experiment with
other sizes later. I found 16 to be a good compromise.
So I think 32/16 is ideal with win98. Your cpu usage will go up,
smaller stripe sizes require the contoller to do more work.
Any comments, corrections, additions?
