1. An information handling system including an increased storage efficiency, comprising:
a first storage resource and a plurality of second storage resources, wherein a reliability of the first storage resource is greater than a reliability of each of the plurality of second storage resources, the reliability based on a reliability factor; and
a processor associated with the first storage resource and the plurality of second storage resources, wherein the processor is configured to:
determine a weight of a file portion;
determine a number of copies of the file portion to be stored based at least on the determined weight;
determine a storage capacity of the first storage resource;
compare the determined storage capacity of the first storage resource with a predetermined capacity threshold;
determine a storage capacity of the plurality of second storage resources when the determined storage capacity of the first storage resource is greater than the predetermined capacity threshold;
determine an adjusted storage threshold when the determined storage capacity of the plurality of second storage resources is less than the predetermined capacity threshold; and
store a copy of the file portion on the first storage resource when the determined number of copies of the file portion is greater than a predetermined storage threshold;
wherein the reliability factor includes at least one of data integrity, restorability, bit error rate analysis, mean time between failure analysis, annual failure rate, age, and speed of the storage resource.
