I got four responses that all said essentially:

"it's written to cache and then written to each mirror at once"

Thank you to:

Follow up question.... Is it then safe to say that a bad disk block on a
disk in a mirrorset should be invisable to the application writing to the
mirrorset? Is the HSx the only place to check for these type of I/O errors?
