    Phoronix: Ubuntu 13.10 Linux Disk Encryption Performance

    It's been a while since last running any Ubuntu Linux disk encryption benchmarks either of the eCryptfs-based home directory encryption feature or the LUKS-based encrypted LVM, both of which are supported by Ubuntu's Ubiquity installer. With having around the System76 Gazelle Professional laptop and its nice Core i7 4900MQ "Haswell" CPU with Intel 520 SSD, and I'm always one to encourage encrypted disks especially for mobile systems, here are some new benchmarks of Ubuntu 13.10 with no disk encryption versus home directory encryption versus a fully encrypted LVM of the root EXT4 file-system.

    Forgetting dual boot in place for better security...my answer is probably a yes

    Hmm, good to know that performance is best with FDE. Now I just have to move these Gigabytes of data to some harddrive and then reinstall my system with FDE through ubiquity. It will cost me, but I guess I'll get what I pay for

      Does LUKS interfere with TRIM/DISCARD? Was a secure-erase performed between test runs?

        LUKS won't ALLOW TRIM/DISCARD unless you explicitly enable it in /etc/crypttab
