      Description

      LZ4 is very fast, both compressing and decompressing, but has a lower compression ratio on average than LZW.
      LZ4HC offers similar compression ratios to LZW (slightly better on average), and decompression speeds are the same (as LZ4).

      Compression is significantly slower though, similar to LZW.

      For use cases where disk space is a premium and reads are far more frequent than writes, this would be a good choice.
