This update completes the Compression Comparison Guide. Finally, 5 years after we posted the first version, we have a new revision of the guide.

This new Compression Comparison Guide takes a look at 11 common data compressors and their performance in 8 different filesets at 3 different compression settings. The result is a detailed but easily accessible look at these data compressors and how they perform with a wide variety of filetypes.

The results of this guide will surprise you. Data compressors that we may have given up as old-fashioned or outdated are actually still highly competitive. Even filesets that you thought was difficult to compress can be relatively easy to tackle.

Read on and find out. We hope this guide will help you choose the best data compressor and settings for your compression tasks.
