Hey,
This is some tests For my Lumia 1520.1, I have tried 2 sdcard:
1. Old 8GB micro SDHC I got from my Xperia Arc S (no brand visible on the card).
Tried recording 1080 30fps (tested for 25 secs) & play, play musics, play 1 1080 mkv & 1080 mp4 movies with each filesize under 2Gb. All smooth!
2. SanDisk Ultra microSDHC Card UHS-I Class 10 (30MB/s) 32GB with SD Card Adapter - SDSDQUA-032G. I bought this card previously for my Gopro hero3 black (worked flawlessly for gopro).
Tried recording 1080 30fps (tested for 25 secs) & play, play musics, play Two 1080 mp4s movies with filesize 1,84Gb & 2,18Gb. All smooth!
Soon I'll have to put those 2 microsds back to their place (old arc s + hero3), so I will have to purchase a new one for my 1520.
I'd like to grab Sandisk 16gb/32gb Extreme Pro for its advertised 95mb/sec, but from what I read here, some people has trouble with theirs. Now I'm not so sure.
Or.... should I just get the same card to (card number 2/Sandisk Ultra 32Gb) for its 30mb/s? Or can I have any noticable performance/speed from the extreme model(anyone with test&confirmation?)?
Thanks.
