You don't need to specify "defaults" when there is any other option present. Defaults is just there so that the column is not empty if you do not specify any option. > /dev/sda2 / ext4 > defaults,noatime,nodiratime,discard 0 1 noatime implies nodiratime. Specifying both is redundant. > /dev/sda3 /var ext4 > defaults,noatime,nodiratime,discard 0 0 > /dev/sdb1 /mnt/donnees ntfs-3g > auto,uid=jacques,gid=users,umask=0022 0 0 > /dev/sdb2 none swap sw > 0 0 Swap on SSD would be faster but I guess you want to avoid the additional writes. > /dev/sdb5 /usr/portage ext4 > defaults,noatime,nodiratime 0 0 > /dev/sdb6 /var/tmp ext4 > defaults,noatime,nodiratime 0 0 > /dev/sdb7 /home ext4 > defaults,noatime,nodiratime 0 0 For home, auto_da_alloc trades a little performance for additional security against stupid applications that forget to fsync(). > /dev/sdb8 /mnt/disk_virt ext4 > defaults,noatime,nodiratime 0 0 Regards, Florian Philipp
