Not without interrupting it,  but prior to that you could have done things
like testing for optimal bs=.  1m should perform ok, but you may have been
able to get better throughput with a smaller value.

If they are IDE drive make sure they are on different controllers eg not in
a master/slave arrangement.

Buy a faster /dev/disk1
