I'd recommend testing the specific application that will run on this system. It's not unusual for a system to preform well in simplistic benchmarks (like bonnie++), but not in real-world use. I recently conducted tests in which a MegaRAID controller handily outclassed software RAID under bonnie++, but fell short under better benchmarks provided by filebench: https://plus.google.com/+GordonMessmer/posts/eSe6iNmk1Fs?sfc=false
