USB 3.0 Raspbmc install

[Zerdusman]

Greetings ladies and gentlemen im new to Linux, the Raspberry Pi, and this forum. I have my PI set up with RASPBMC on a 3.0 stick and i love it! It works great! but i do have a question: I build mt pi to be a portable media player so i planned to have a micro USB card reader for movie files in my second USB port. Since Ive instead decided to to use that 2nd slot for an air mouse, is it possible I can upgrade the USB 3.0 flashdrive the Raspbmc is installed on to a 128GB and stor movies on that?

With Berryboot you could install the OS on USB HDD/SSD of big size, but not that it will be limited in speeds to USB2, and may need powered USB HUB if it will be more power demanding.

The Raspberry Pi only has USB 2.0 ports, no point spending the extra money for USB 3.0 speeds that the RPi won't be able to make use of

USB flash drives (and USB hard drives) all use a common Mass Storage Device interface, so any variety you plug in should "just work"

I don't agree that a 3.0 stick is a waste. Yes the Pi only has 2.0 ports, however 3.0 sticks tend to have better controlers and faster nand. A most 3.0 sticks will consistantly outperform a 2.0 stick in a 2.0 port. Plus if you decide to stop using your Pi you have a 3.0 stick.

Not all is cut and paste though I did benchmark one 3.0 stick that was slower plugged into a 2.0 or a 3.0 port. That was a 32GB Kingston Datatravler 100 G3. There are many 2.0 sticks that will outperform this thing. On the other hand I have a Mushkin 3.0 stick (don't recall the model) that saturates a USB 2 bus easily and has excellent iops plus when plugged into a 3.0 port will hit 85 MB/sec which isn't bad for a first gen drive.
