RAID-5/Stripe Size and verifying absolute disk stripe access

My problem is aligning reads/writes properly on a 3 disk RAID-5 volume
with stripe size of 16384. Since my measurements all show the same
relatively low read/write performance on the volume matter which offset
i choose on the disklabel "partition" (i've tried with the granularity
of a single sector and the results are the same).
In FreeBSD 7.0-RELEASE, is there any way to find out a absolute
read/write sector location for the beginning of filesystem within a
disklabel "partition"?
