Running storage from USB

[shortskoolbus]

Hello Folks,

Pretty new here to the RPI and Xbian, have tinkered with XBMC before on an old laptop... but in general also kind of a linux command line noob, but can usually figure things out from the internet.

So i've been doing some reading and over on the openelec forums, people were talking about moving the storage to a USB drive, but still booting from the SD card. They reported performance gains from doing so, and I'm just wondering does it make the same to do so with xbian?

I couldn't find any posts around here discussing that. And if so, is there a writeup somewhere how to do it?

Thanks!
Kelvin
