The hit to iop performance is mainly due to the large number of cores in
the the high end Intel cpu. I suggest you find a nice 4-core Intel
processor, something non-extreme. you'll find all your IO will improve.

Again, if you're serious about RAID, get an LSI MegaRAID card. While I
have my dislikes about the LSI controller, it's a lot faster than using
MD and much faster (and more reliable) than any bios software RAID.
Oh, and don't believe all the published numbers on drives,
etc...benchmarking is an art.
