| Storage I/O comparison
To obtain the results in the storage I/O comparison graph, type the following lines at a command prompt. The first command tests the write speed, and the second command tests the read speed:
$ dd if=/dev/zero of=test.tmp oflag=direct bs=500K count=1024
$ dd if=test.tmp of=/dev/null iflag=direct bs=500K count=1024

Media access performance | RPi2 Model B | ODROID-C1+ | eMMC Read (MB/s) | NA | 62.2 | eMMC Write (MB/s) | NA | 25.1 | MicroSD UHS-1 Read (MB/s) | 19.2 | 32.5 | MicroSD UHS-1 Write (MB/s) | 13.1 | 14.2 |

| If you use the eMMC storage, you can get about two to three times faster storage I/O read performance. However, an affordable microSD UHS-1 card can still achieve reasonably fast speeds thanks to the advanced SD 3.01 host controller in the S805 processor. The MicroSD card read performance on C1+ is still about 1.7 times faster then RPi if you use the UHS-1 memory card. |
