USB or SD Card for gamelist.xml & images/snaps

@almulder I keep it all on the USB because if I ever reimage I never have to scrape them again, just a basic plug and play at that point

@clyde Thnaks for the info I will test this this week and find out. :) Just got a high end SD with fast read write and was going to OC the SD card reader. eo see what is faster or how far apart they are. :)

@almulder Be sure to repeat each test a couple of times (3-5 should suffice), because they tend to fluctuate a little. Also, the non-cached values should match real conditions more, since the cache shouldn't count much if the data hasn't been read before.

Although the Pi's USB 2 ports do limit modern hard drives severely, my Samsung EVO 840 ssd beats my Toshiba Exceria Pro U3 sd card with approx. 36 MB/s to approx. 22 MB/s non-cached reading speed.

Also consider @herb_fargus' point about portability.

Just incase anyone wants my numbers: Ran each test 10 times and got the average.

I had been wondering about this, thank you!

[almulder]

Going to create a script people can run so they can test it without knowing command lines.

@almulder Good idea. :)

[almulder]

Ok I have created the script if anyone whats to try it out.

Let me know what you think.

@almulder I will, but not immediately, because I'm about to leave. Stay tuned.

One small thing I noticed in your README.md: In this sentence, there seems to be something missing before the word drivetest.png:

Anyways grab the file drivetest.sh and put it in your ./home/pi/RetroPie/retropiemenu drivetest.png and put it in your ./home/pi/RetroPie/retropiemenu/icons

Thanks it was the way they format what I type in. I modified it for easier reading.
