Android unusable, were my expectations too high?

There shouldn't be any crashing, but the performance difference cards can be 100x for small random reads, and that includes branded cards that meet modern standards, because the standards only talk about sequential performance.

That means something that takes less than a second on, say, a Samsung Evo, may take over a minute on a SanDisk U3.

So yeah, application not responding is very likely, although it may get there in the end if you're patient enough or it doesn't forcibly timeout.

I now solely use ''SanDisk 16GB U3 Extremes'' which work flawlessly while the community recommends Samsung EVO+. I think whichever you buy you will be on the safe side.

The point here is that you should not worry about your Pine64's performance on Android. The experience you had so far has certainly nothing to do with the board's normal performance. Smile

It's a genuine SanDisk according to that app, but comes up as a 63GB SL64G rather than a 64GB SU64G like my others? Maybe SanDisk themselves have started selling inferior cards in their Ultra line. I tried it in Crystal Disk Mark (on 2 different PCs) and the random read/write results are terrible, much worse than even the PNY card mentioned in the thread benpope81 linked above. I'll go and buy an EVO+, thanks Smile
Most of Sandisks ultra cards have ten years warranty. Register your card on the Scandisk website and then you can see the warranty status. The replacement service is fine, normally 3 weeks.

The problem will be making the case for it actually being faulty. It does still deliver class 10 speeds, even if it's slower than my other cards. I bought it months ago (at the time I ordered my PINE) unfortunately, or I would have attempted to return it to the shop I bought it from as that would probably have been less problematic.

Glad to know, I have several Sandisk microSD cards need to claim, especially 64GB cards.
