Storage I/O comparison 

The C2 can boot from a MicroSD card or an eMMC module. The MicroSD interface supports the higher performance UHS-1 mode as well. File access of a 512MB file (read/write) on two different storage options shows distinct performance differences. The eMMC  storage is ~7x faster than the MicroSD Class-10 card in read tests. The MicroSD UHS-1 card is ~2x faster than the MicroSD Class-10 card in read tests. The MicroSD UHS-1 card provides a great low-cost option for many applications
