No, you're right, hdparm is raw r/w and sees no FS. Slipped my mind for a
moment.

You can have one extra disk for this benchmark, and time operations on them.
Might want to follow http://www.debian-administration.org/articles/388 as
closely as possible, with the exception that you're comparing only two of
them. I might try this on an external disk, where the bottleneck is the
USB/interface speed, but FS differences can still be observed.
