I would generally agree that dd is not a great benchmarking tool, but you could use multiple instances to multiple files, and larger block sizes are more efficient. And it's always good to check iostat and mpstat for io and cpu bottlenecks. Also note that an initial run that creates files may

Hello All, Sorry for the lack of information. Here is some answers to some questions: 1) createPool.sh: essentially can take 2 params, one is number of disks in pool, the second is either blank or mirrored, blank means number of disks in the pool i.e. raid 0, mirrored makes 2 disk mirrors.

What sort of load will this server be serving? sync or async writes? what sort of reads? random i/o or sequential? if sequential, how many streams/concurrent users? those are factors you need to evaluate before running a test. A local test will usually be using async i/o and a dd with only 4k
