For a prototype, yeah, using an RPI would be the sweet spot.

If you want to build hardware that is dedicated to just SD to external 
harddrive transfer and just getting started in hardware, you probably don't 
want to jump in head-first with building a board with full embedded linux on 
it. You'd be able to make the thing super cheap with less overhead than full 
linux with:

* Some microcontroller
* An SD card socket
* SATA socket
* Implementing SATA and MMC either through another chip or implementing 
directly on the microcontroller.

After that you'll stare longingly at the OMAP 5912 and get caught with the bug 
of embedded electronics engineering.

Here's some teaser links to get you moving:
