I agree with "adaptive compression" NetApp: Adaptive compression divides the file to be compressed into compression groups of 8k blocks. This compression group is then compressed and stored as a single block. When a user requests data from this compression group, it takes much less time to decompress and provide that data to the user, thereby improving the read performance.
