I did a small and partial (no restores) benchmark of several image programs, and want to share the results, which are in the attached image. I created and verified an image of the system partition (Windows 7 x64) of this computer. In all cases I worked outside of Windows (my normal practice), using the 64-bit WinPE 4.0 boot medium created with WADK for Windows 8. I used default compression and created a single-file image (no splitting) in an external USB 2.0 disk connected to a USB 3.0 port (so, working at USB 2.0 speed). I had never worked with either Reflect or IFW, but in both cases I could create the image in the first try, without problems.
