AFAIK UFS try to spread data quite evenly on disk to different cylinder group - for large files, so small files can get it's space near inodes etc.. but i would like to clear things up: i will set up say 3 disks with gconcat and make one partition for all data on it. then i will populate it with all things and use it. will the data be quite spread on disks, so accesses to different things could be done in parallel to 3 disks, or will it rather use space on one disk first, then on second then on third. i'm asking about it as i prefer gconcat over gstripe as i can add more disks to gconcat and do growfs then making system EASILY expandable.
