Which SD card is better, higher read or write in 4K benchmark?

I did.but whole video lags!maybe S912 is not capable of this heavy video!

S905X and S912 are only just fast enough for 720p in Netflix.

Hehehe…, no wonder. Even Odroid N2 has problems with this series. Works OK in 1080p only with old widevine.

But I installed old widevine also.So my experience with Vorke Z6 was:Lag both on hd/full hd with an old kingston class 10 with 2MB read random speed.And no lags on hd/full hd with brand new Sandisk extreme pro with 4,1MB read random speed,except on some full hd videos like this documentary but they run perfect on 720p.(Maybe they are decoded with other heavier way,who knows)

Will this sd card be somewhere same performance as emmc if used in the odroid n2?

All I do i stream, only thing that would be stored is thumbnails for content.

You’re good with that SD Card.
