===Low compression ratios===

One of the primary issues is the degree to which the contents of primary storage can be compressed under real-world loads. Program code and much of the data held in primary storage is often not highly compressible, since efficient programming techniques and data architectures are designed to automatically eliminate redundancy in data sets. Various studies show typical [[data compression ratio]]s ranging from 1:2 to 1:2.5 for program data.<ref name="SIMPSON"/><ref name="RIZZO"/>
