But disk bandwidth is so incredibly expensive that compression becoming more and more useful: on compressed file system bandwidth of user-data transfers can be larger than raw disk bandwidth. It is the same situation as with allocation of disk space for files: disks are cheap, but storing several files in the same block becomes more advantageous over time.
