Apart from the filesystem tests, you may want to repeat the RAID testing with a combination of three hardware-mirrored pairs striped together using software. At least under Linux, I would predict you will see the performance increasing by 20% or so, due to the combination of the utilization of the hardware cache plus parallel kernel I/O queues. I don't have experience of a similar configuration under Solaris, unfortunately.
