    11.10 Install on SSD?

    I've located two SATA identical 100 GB SSD's and I'm wondering if it's OK to load 11.10 on them? I've never used SSD's and I have no idea if Linux or 11.10 for that matter can utilize the drives efficiently with use of the TRIM command or some other garbage collection mechanism...

    Can anyone tell me if I can use my SSD drives on 11.10 or if I should continue to use my 1 TB spindle drives instead.

    Thanks!

    It's not a concern. Ubuntu had full support for SSDs (including TRIM) since 10.04 or maybe even earlier.

    Re: 11.10 Install on SSD?

    I was told my other forums / distributions that in order for this to work, I MUST use EXT4 file system ONLY and I would need to use the DISCARD option in /etc/fstab. Can anyone please explain and or clarify on this for me?

    Re: 11.10 Install on SSD?

    I just installed to a 60GB new SSD, with 2 30GB partitions ( and a tiny bios_grub) so I can rotate my new install. Data is on spinning drives.
    Since it is and will only be Linux I used gpt as the partitioning scheme as recommended byt archlinux site.

    You want journal to speed up system recovery if you have to do repairs or run fsck. But if partition is small then it does not take long to fsck anyway and without journal writing is reduced.

    Re: 11.10 Install on SSD?

    Hello,

    I bought a SSD today on the internet, and I was wondering what filesystem I should put on it. If I install 11.10 with BTRFS, is TRIM automatically activated, or do I need to edit the fstab like for ext4?

    I am running 120GB SSD on Ubuntu since 10.04 with no problem at all, upgraded fine to 10.10, 11.04 afterwards of course.
    The only trick I applyed was to add the "noatime" option for the drive in /dev/fstab. Several forum topics explain the good part of this applied to the relatively limited life of SSD drives.

    Re: 11.10 Install on SSD?

    TRIM/Discard appears to ONLY support EXT4. I'm still not clear based on this post if I must enable TRIM support in some configuration file or if it works out of the box from a fresh installation...anyone?
