How can the Arduino emulate a USB storage device?
I found out that Arduino can emulate a USB device, the Arduino Leonardo even out of the box. The LUFA USB stack can be used on Arduino and it implements a USB mass storage device driver (see this tutorial ). This setup could be used to map USB to SCSI commands such as understood by the SD card reader.
Can a Raspberry Pi be used as a NAS?
Using the Raspberry Pi as a NAS box basically does exactly what you asked for but instead of using USB it would be using your network. Here are great instructions on how to do this if you are interested. I can do it with my old Nokia N900 Phone using the usb gadget driver included with the stock Nokia kernel.
