A method is revealed to optimize the performance of a computer by establishing purpose-specific sections in its main non-volatile storage medium. This method creates a basic set of purpose-specific sections in order to store, separated at a physical level and at a logical level, basic elements associated to equipment operation such as operating system, dynamic files, applications and user related files; and, optionally, creates an additional set of purpose-specific sections to store other elements separated in like manner. A secondary method is also described to supplement the previous one, in order to quickly optimize an unlimited number of identical computers. In addition, the optimized main non-volatile storage medium that results from employing either of the previous methods is described. For users, owners and technicians of an optimized equipment, the use of this invention generates numerous advantages, including minimized file fragmentation; better defragmentation techniques, and improved operating speed.
