You ran a check on the array and then checked mismatch_cnt?
like
~# fsck.ext3 -y -v /dev/md0 ??

Can I se the sata_sil parameters?
Or test something there?
For me it shuld slow don a bit more.
Run a check on the array:
p34:~# echo check > /sys/devices/virtual/block/md0/md/sync_action
I found /sys/block/md0/md/sync_action
idle
I don't find 'check' i my box, but I run this every 2nd day, it help a bit.
/etc/cron.d/mdadm/
...
5 0 * * 1,3,5 root [ -x /usr/share/mdadm/checkarray ] \
&& /usr/share/mdadm/checkarray --cron --all --quiet
...
p34:~#
Watch the status:
p34:~# cat /proc/mdstat

When its done, run:
p34:~# cat /sys/devices/virtual/block/md0/md/mismatch_cnt
/sys/block/md0/md/mismatch_cnt 0
p34:~#
And show the output.
