MuMetal appears to be the industry standard for magnetic shielding as found in hard drives. It works well. According to wikipedia however, metglas has a much higher magnetic permeability with permiability of 1,000,000 vs 20,000 - 50,000 for MuMetal. https://en.wikipedia.org/wiki/Permeability_(electromagnetism) I may be overly naive (which I probably am) , but wouldn't this suggest that you would be able to have a much thinner shield with Metglas?
On the Metglas website they don't sound like they are playing it up very much.

"Generally speaking our METGLAS 2714A alloy is better than Mumetal."
The saturation only seems to be .57 Tesla but still with permiability of 1,000,000 that has to count for something?
