Let's say I am mounting a WIM image on Windows using dism:
dism /Mount-Image /ImageFile:D:\work\sources\install.wim /Index:1 /MountDir:E:\work.tmp
Here, D:\work is the "source" directory (containing extracted contents of a Windows installation disk) and E:\work.tmp is the scratch directory.
My intention is to carry out modifications (apply updates, integrate drivers, edit registry) to the image. I am interested in reducing the time it will take me to carry out those modifications (that is, speeding up I/O to the mounted image).
With respect to I/O performance to the mounted image, does it matter if E: is a slow disk or a fast disk? Why?
