recommended micro sd card ?

[tllim]

I just loaded the newest Android image to this new card.  Very stable

Isn't it funny that using an SD card with ultra slow random writes even leads to Android behaving unstable and that problems are gone when using any recommended SD card that shows high random I/O performance?

And still only bullshit recommendations like 'speed at least class 10' available in Pine64 wiki leading to all sorts of troubles for their users. But why should this change? Why spending a minute on improving documentation when their users can waste hours and hours of their live due to missing/wrong recommendations.

BTW: With the 16GB test something clearly went wrong and you should keep in mind that when the card is used inside Pine64 the board's SDIO implementation limits sequential transfer speeds anyway to 23MB/s max. All the numbers here also apply to Pine64: http://forum.armbian.com/index.php/topic...rformance/

Thanks on your comments and inputs, I have post on wiki page that on your random R/W factor recommendation. This is a good fact and a lot of people, including myself, overlook.
