recommended micro sd card ?

[xrez]

I Just tested a class 4 8gb card from transcend vs a kingston class 10 uhs1 16gb and for some odd reason the 8gb slower card runs things a LOT faster... is there any reason if the card is bigger it will be slower?

It's quite the opposite if you choose quality cards (see the link I posted in this very same thread). And also the so called 'speed class' is close to irrelevant since we're talking about computers and not digital cameras (sequential I/O is important for cameras, random I/O is important for computers). 

And then you shouldn't compare quality vendors (Transcend) with nonames (Kingston).

Only 4 vendors produce their own NAND dies, their own controllers and combine both to retail products: Samsung, SanDisk, Toshiba and Transcend. Buying anything else is simply a waste of money since you NEVER know what you get: The cards might show the irrelevant sequential transfer speeds they're rated for but fail providing high random I/O speeds.

Gotcha. 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?
