I'd like to have some portable OS X installation that I'll be able to use with different machines (MacBook at home, MacMini at work, etc.) I installed Mountain Lion on my 32GB class 10 SD card recently. On disk intensive applications this setup feels a little bit sluggish.
May be it's possible to setup RAID-0 with SD card and machine's internal HDD. Will it work and speed up overall disk IO?
And what will happen if I shutdown and eject SD card from some machine and insert it to another one which internal HDD is still unsyncronized with SD card?
