I use named pipes on my backup script.

I dd a hard disk partition, compress it, and at the same time calculate a checksum.

     mkfifo mdpipe
     dd if=/dev/$1  status=progress  bs=16M | tee mdpipe | pigz -3 > $3.gz &
     md5sum -b mdpipe | tee -a md5checksum_expanded
     wait
     rm mdpipe
     echo "$3" >> md5checksum_expanded

This way there is only one disk read operation. I can see the thing running at max hard disk speed.
