With trim/discard enabled, SSD's lifetime can be increased and write performance may be improved. For common users, we can't expect them to know trim and enable it manually, so it is better to let ubuntu do it automatically like below: - check if the disk support trim by hdparm -I - if the disk supports trim, either mount with '-o discard' or doing trim in background periodically as suggested in below link[1], or other better way [1], http://blog.neutrino.es/2013/howto-properly-activate-trim-for- your-ssd-on-linux-fstrim-lvm-and-dmcrypt/ To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1244504/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
