Abstract

All modern devices have a huge amount of storage available for use. Normally the storage repository (hard disk) is filled from the low storage location addresses to the higher ones. It occurs that the low memory addresses are used and reused several times, while the high storage addresses are seldom used, or maybe never during the device life. One of the reasons of hard disk breaking is the repeated use of the same sector track location, written and rewritten several times. Using the disk space more efficiently might help to reduce the disk breaking or sectors damaging due to hard use.

System to Optimize Disk Life

Hereafter it is described a system and a method which basing on gathered statistics, periodically directs the data storing to a different starting location. Basically it switches the available storage start with a different (initially higher) unused storage address, This allows an average use and consumption of all the available storage locations in the disk. This will help to extend the life of the disk drives. Normally the disk is empty (fig. 1), without user data (we are not referring to the disk or disk partition used by the OS).

The proposed system monitors the use of the disk space (fig. 2), and how many times a sector of storage is referenced for I/O. When the space allocation reaches a certain threshold (Fig. 3) or periodically after a certain amount of disk use (if the gathered statistics are confirming the need) the system moves all the stored data to a new start location. Normally it is preferably done before shutting down and after preventive User consensus and after having verified that the proper pre-requisites are in place (like battery duration, enough space to perform the copy, no other background active disk processes, etc ), or can be done as follow up activity after some commands (like system defrag or system backup. Or it can occur independently via dedicated user command, and the storage area is copied as is (with its holes) into the new area). This new target copy location will be the new "zero" storage address, until the...
