Does applying these tweaks to the sdb raid harm any data that is already on the array?

echo 64 > /sys/block/sdb/queue/max_sectors_kb
echo 512 > /sys/block/sdb/queue/nr_requests
echo deadline > /sys/block/sdb/queue/scheduler
echo 20 > /proc/sys/vm/dirty_background_ratio
echo 60 > /proc/sys/vm/dirty_ratio
blockdev --setra 16384 /dev/sdb

Thank you

No, those changes are non-destructive.
