The reason you did not find that specific information is that it does not really matter. When editing you do not access documents at the same time, whether they are .DOC, .DOCX or .XLS files.
In my personal case I have My Documents on a network drive, not on any local drive. That allows me to sync the complete folder with my laptop as well, so I always have full access to My Documents when on the road.
Thank you, Harm, for your timely response.
For now, then, in accordance with your Guide's four-disk recommendation, this will be my setup:
- [OS, Programs] on a Crucial M4 256GB SSD
- [Media, Projects] and [Previews, Exports] on a two-disk Aid0 drive (2x1.5T WD Black Caviar)
- [Pagefile, Media Cache] and My Documents on the 4th disk (a single 1.5T Black Caviar).
