Hi list,

I'm considering using a bootable USB stick with FreeBSD to perform a backup of my notebooks' 500 GB hard disk to a physically identical (same make, same type, same size) hard disk attached to USB.

What would be the fastest way to do that sector by sector copy? I'm using dd right now,

dd if=/dev/ad0 of=/dev/da0 bs=10000000

but maybe there is a utility which does this faster or a larger buffer size? Probably the limit will be
the USB 2.0 bus speed anyway?
