Would a RAID mirror work? Not sure if you can have more than 2 devices in a mirrored array, but you can look at mdadm:

Subject: [Novalug] DD Command
Does anyone know of a way to copy a single DD input file (disk) to multiple output files (disks) simultaneously?
I'm trying to avoid the read bottleneck by reading once and piping that to all of the writes. I have a bunch of laptops from a training lab and this will save me a huge amount of time if it can be done. I'm familiar with DD, netcat and SSH, but I only know how to pipe a single input file to a single output file.
