It kicks ass.
Just finished running lots of tests with it for work. Best disk imaging software I ever used.
In under 30 minutes I was able to create an image of a broken down laptop's hard drive and load it onto a VM (the image files work in vmware workstation).
In a similar amount of time I backed up a desktop with a 500GB drive (with about 30GB used), and then swapped out the disk for an 80GB one, and it worked fine and handled the disk size difference perfectly.
I backed up a VM and loaded it into a physical machine, which often has some issues with Windows.
So anyone interested in disk imaging I suggest using this. It has a stand-alone boot CD which is what I used, don't care about the installed version.
Get it legally or pirate it, don't care either way. Lucky for me I get to use NFR (not for resale) licenses from work.
