Hell no. ReiserFS is a
tree structure. That link talks about the new system in v4, but it uses the v3 system as a comparison if I am not mistaken.
Anyway, because of the tree structure used ReiserFS is the fastest file system out there when it comes to finding files. It also implements a journaling system that works much better then the NTFS system.
Tell your professor he might want to read up about what he is talking about.
