Public bug reported: Many filesystems support discard feature, and lots of SSD disks(even some usb storages) support TRIM feature, but unfortunately Ubuntu does not enable it automatically.
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/ ** Affects: linux (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1244504 Title: need to enable trim for SSD disk automatically To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1244504/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
