Also what software did you use to benchmark your drive subsystem?
Bonnie++ is a good place to start. There are better suites out there
but it's been a while for me since I've used them.
Also note the HP i410 is not the fastest RAID controller ever, but it
should be faster than this if it has a battery backed cache on it
which will allow write-back operation. Without it the controller will
default to write-through, which is much slower.
