That is still weird -
But all your numbers so far are coming from bonnie. Why don't you do a test
like this? (below)
Write a big file to mirror. Reboot (or something) to clear cache. Now time
read the file.
Sometimes you'll get a different result with dd versus cat.

I don't have bonnie, but I have certainly confirmed mirror performance on
solaris before with sata disks. I've generally done iozone, benchmarking
the N-way mirror, and the stripe-of-mirrors. So I know the expectation in
this case is correct.
