recommended micro sd card ?

[tkaiser]

Hence why im trying to find an alternative to the samsung microsd cards

One last time: The most important factor for SBC (or Android device) performance is random I/O with small record/block sizes. This is not related to the 'speed class' ratings and cards of the same speed class show differences in the range of being 20 times slower (or even more).

So all you can do is to rely on real measurements done within the last few weeks/months. At Armbian we've done this, others have done this. Forget about any cards listed there that are older than 6 months since in the meantime newer controllers or NAND dies could be used. Here you find the results of different test runs: https://github.com/igorpecovnik/lib/blob...re-sd-card (the tests made by Armbian users being the 'best' for Pine64 since already taken the sequential speed limitation into account)
