I’m testing eMMC 5.1 performance and I’m noticed slow sequential write on it.
In spec emmc 5.1 will have sequential write about 125MB/s and sequential read about 250MB/s
I got results (using dd):
time sh -c “dd if=/dev/zero of=/home/file bs=4k count=200000 && sync”
wrtie : 35MB/s
echo 3 > /proc/sys/vm/drop_caches
time sh -c “dd if=/home/file of=/dev/zero bs=4k count=200000”
anybody can confirm it?
