Operating System Linux for ODROID-XU4 (Pre-installed Ubuntu15.04 or latest version).
Ready to run out of the box
Many nano-computer does use a microSD card to boot and starts the operating system. This is the case for the Raspberry-Pi and OlinuXino.
ODroid can also start the operating system from the SD card... but it also exists the eMMC solution which offer better performances.
SD vs eMMC performance
You 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 three different storage options shows distinct performance differences.
The eMMC 5.0 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!
