Well, to me a big advantage of booting from SD is that you can
actually quite easily already get cards from 8Gb. I would like for
instance to have one with Windows on there so I can easily flash in a
new BIOS when needed.
Also: an sd card doesn't stick out if the machine, limiting the risk
of damage/bumping it.

best regards,
