Although it may be overkill for the application, considering its capacity, this appears to work very well for firmware memory for the Raspberry Pi, and at the price I bought it for on last year's Cyber-Monday, I wish I could buy a few more of them for the same price.  I haven't tried it with the RPi overclocked, but it's worked without a glitch at the normal RPi clock rate.  I've also used the 32GB version of this in my music player, and it has worked well also.
