recommended micro sd card ?

[xrez]

So mostly the numbers usually just help digital cameras and not really anything else. Also did not know that Kingston would be considered a noname since they have been in the memory business for a long long time. So if i got another transcend class 10 i would see a difference from my class 4 one?

The 'speed class' is only about guaranteed (mostly irrelevant) sequential transfer speeds. And unfortunately there exists no such thing describing the random I/O performance.

The only Kingston products I would buy is server DRAM but never SD cards: http://www.bunniestudios.com/blog/?page_id=1022

Regarding Transcend: No idea since you would have to test the card in question. We at Armbian spent some efforts on testing through different cards using identical conditions but there weren't that much Transcend results. If I would've to buy a new card for any Allwinner based SBC (like Pine64 for example) now  I would definitely again choose a simple Samsung EVO with 32GB or above (the smaller sizes show lower performance. And they're rated to give you 10 MB/s sequential write speed max but all tested EVOs with 32 or 64GB exceeded 21MB/s in reality). Again:

Thanks for that Tkaiser. I'm still new at all of this and has been educational. Over here a 16gb evo card costs about $23 usd vs the cheapo Kingston at about $6 usd. I will be trying a $7usd samsung card (http://www.amazon.com/Samsung-Class-Adap...B00IVPU6L4) and report back. By the way if i wanted to compare random i/o speeds of these cards is there a program that i could use? Preferably windows based if possible
