I would agree this would seem to be the best solution for PS temporary files
and image scans that have the original film as backup.

Also consider that striping doubles your chances of losing your data (EITHER
drive failing will lose ALL your data). Data access times are roughly the
same as a single drive it is only the transfer rate that doubles (the most
important bit for large data transfers like film scans).

With some mirrored controllers only writing is slower. Read operations can
be striped if the hardware/software implementation is clever enough. On
average you read files more often than you write so with a smart controller
you get  very slightly slower writes, but almost double the transfer rates
during reads.
