Its probably worth playing with vfs.zfs.cache_flush_disable when using the hardware RAID.
By default, ZFS will flush the entire hardware cache just to make sure the ZFS Intent Log (ZIL) has been written.
This isn't so bad on a group of hard disks with small caches, but bad if you have 256mb of controller write cache.
Ok.
