so everyone else's suggestions have been good , but my suggestion
will be different . 

the issue is you have a process that wants to write . (or read , but
i'll bet it's trying to write) . what you -should- do is get an ssd that
is super fast and able to handle the writes and then have an extra
process who's job it is to copy data to the other slower drives . 

your job is probably to be a grad student , not solve i/o storms .
