Mountain out of a mole hill. Glad someone got some sense knocked into them and enable this flag by default, but Linux has supported TRIM for a long time. It was just a matter of adding the mount option. And by the way, last I checked there's still a long laundry list of non-default incantations to optimize SSD usage on Windows, where you're stuck harder because you don't have control over things like the I/O scheduler.

  Here is a great guide: http://www.overclock.net/t/1156654/seans-windows-7-install-optimization-guide-for-ssds-hdds http://www.overclock.net/t/1156654/seans-windows-7-install-o... :)

    I didn't notice any genuinely bad advice when I gave that a quick once-over, but I'm pretty sure none of it is actually necessary to make TRIM work on Windows 7. Verifying the AHCI setting in the BIOS is good advice but might not always be necessary, depending on the SSD.

      TRIM is just one component of an optimal SSD configuration, and it's somewhat overrated. It should be on by default, but it's not the only consideration for good SSD performance.

        Is there a more important factor than TRIM in preventing performance degradation over time? (aside from just not letting the drive get too full) It _all_ might be somewhat overrated. I've certainly never worried much about all this stuff, and my SSDs still perform phenomenally well. I used one in my old Macbook well before OS X supported TRIM and all was well, although I have to admit that on another machine I thought for sure Linux was taking care of TRIM for me. Apparently not.

    Looks 99% BS to me, and the other 1% seems to be unnecessary. Would you mind listing the items you think are actually necessary here, instead of pointing me to a 489-page forum thread?

      From near the top of the opening post: A quick word on SSDs: SSDs do NOT require the confusing and intense setup that a lot of people seem to suggest. The current day SSDs are much more reliable and literally all that is necessary is to change the SATA mode to AHCI or RAID in the BIOS/UEFI, install, and you are good to go.
      - justin66 13y ago
        Even the move to AHCI isn't strictly necessary with most drives.

        Yeah I saw, it made me wonder why @shocks linked me to it...

AFAIK the "fstrim" option will be used and the "discard" flag will not be enabled by default.
