The file caching algorithms in DOS and OS/2 were patented technology of IBM. Microsoft was not permitted to use them (that is why Microsoft *never* had any sort of disk cache that ever worked, even in DOS), plus Microsoft is a Low Wattage company. OS/2 had IBM cache technology in it which worked properly. However, when Microsoft broke the Joint Application Development Agreement with OS/2 New Technology 2.0 (which they renamed to just "NT") Microsoft had to remove all of IBMs code and write their own. As I said previously, Microsoft is pretty low wattage when it comes to understanding how and why things work and how to make computers work efficiently. After all, they do stupid shit like optimize for maximum CPU usage, and then put that in their documentation as a crowning achievement.
