Woody...yes the Piriform product has a different algorithm for compression. I'm not technically savvy to explain how it differs but can give an example. Using my Win7x64's built in defragger, it said there was 0% fragmented files. Using the Piriform defragger, it said there were 13% fragmented files. Be forwarned that the Piriform defrag routine, while very good, is lengthy, my 1TB drive took over 20 hours.
