Probably a basic question, but my searches haven't yielded anything definitive.
I just got my pi a couple of weeks ago, and installed OpenELEC. I'm using a usb drive as storage, as I understand it performs faster this way. I used the instructions from the OpenELEC wiki:

Now, it's mentioned in the instructions that if I want to upgrade OpenELEC, I just need to download the new version and replace the relevant files on the SD card.
What about updating via the interface? I'm getting messages from the auto updater that there's a system update available. If I let it install the update, will it replace the relevant files and keep the SD card plus USB structure intact?
