Why buy a HW cloner when you can do it faster with free SW?
https://www.macrium.com/reflectfreeI have used this SW for over a year and love it. I use it to create nightly backup images of all of my Windows PCs to a backup server through the included scheduler. It can also clone any OS disk (including Ubuntu - nvOC) and even Windows Server if you boot from the PE image. If you want to roll out the same image to a bunch of machines, just create an image and then restore it multiple times.
Hope this helps.
DD is even more "free" since it's a standard LINUX utility included in EVERY LINUX version released (to my knowlage) since at least Yggdrasil.
It will clone ANYTHING - though cloning a bigger drive to a smaller one will obviously have issues if you have too much data on the bigger drive.
