I do not know what clustering would do for you. But striping will
provide a
high level of assurance that each of your hard drives will process
equivalent
amounts of IO operations.
I don't know what I'm talking about, but wouldn't mirorring be faster
than striping for random reads like you often get on a database ? (ie. the
reads can be dispatched to any disk) ? (or course, not for writes, but if
you won't use fsync, random writes should be reduced no ?)
