> How much space is wasted due to partially filled filesystem blocks? This is less important with today's workstation drives than it was 30 years ago, but perhaps still relevant on a single-board computer with limited flash storage, for example. I store my e-mail in a maildir on ZFS with compression enabled. I have not tuned it in any way. My archive directory is 30% smaller than the total number of bytes according to "du" (i.e. compression outweighs the space overhead) For a more "normal person" comparison, I made a fresh ext4 file-system and copied it over and used "df" to get the exact number of blocks in use; overhead was about 2%. Seems fine to me. [edit] Median file size is 5744 bytes, 1/10/90/99 percentile sizes in bytes are 1777/3050/41059/169654
