Release: Yocto-Morty (4.9.51_GA)

Board: i.MX8MQ EVK


I have tested eMMC performance on iMX8MQ EVK board using dd & hdparm and I observed that read speed is approx 135-140 MB/s and write speed is approx 20 MB/s. While referring eMMC datasheet it mentions that eMMC performance as below image.

So, what is the reason I have got that much low performance?
