Sony Xperia Z2 maximum supported write/read speed for MicroSD Cards

[dainiska]

I am looking to buy one microSD card for my Xperia Z2 Phone (6503). My question is:  how fast it can write data to an SD card. For what I know, these speeds depend of SD Card controller. If I will know approximative numbers I can acquire adequate microSD card. Right now I am trying to decide between: SanDisk SDSDQX-064G-U46A Extreme Plus 64 GB - 80 MB/s SanDisk SDSDQUA-128G-G46A Ultra 128 GB - 30MB/s Writing speeds for these microSD Cards are half of indicated reed sped numbers. I like 128 GB capacity of Ultra Card, but will not hesitate to buy faster 64 GB Extreme Plus Card.

If you use 4K recording like features, you might need to get a high speed SD!(go for the Maximum speed you can)

So I think Extreme plus would be better in this case, but if your phone is everything for you (just like me) use the maximum capacity (Which has a better speed as well, otherwise useless) I use a class 10 128 GB!

As far a I know, I think even 30 MBP will be enough for a 4K video!

Yes yes!

30 MBPS is more than enough for recording 4K videos!!
My one has a speed of 10 (minimum), but still I record 4K without any issu!

4K requires about 7MB/s write speed, so do not worry, you will be good.

Indeed,consider at least class 10 microSDHC(SDXC > 32 GB) if you want to enjoy 4K.4K bitrate is somewhere around 54 Mb/s~7 MB/s as azzido said.

Check out the forums re SD cards being "fried" by the phone (it happened to my 64gb San Disc) before you shell out your hard earned for an expensive one.
