Well, that's what Google came up with when I googled for ways to measure eMMC read speeds.

From your results it can be easily deduced that the throughput bears little relation to the media which is a bad benchmark if you are trying to compare media. When dumping a 1G file bs=4M is my preference but I still wouldn't use dd to benchmark.
Just tried it with bs=4M, that's showing better read speeds: ~57MBps.
