One thing: 1m is a bit small for modern systems. Or for not-so-modern

more is perfectly reasonable.
It won't go any faster..
In a modern system the CPU is so much faster than the disk than anything above
about 16k would be enough.
I found 64k to be optimal (e.g, max performance) on most machines
I heard its faster if you use two dd's; i.e:
# dd if=/dev/ad0 bs=64k | dd of=/dev/ad1 bs=64k
allowing read and write to proceed in parallel.
