microSD card for 4k recording

[overzeetop]

Has anyone recorded 4K video from the G3 onto a uSD card? I'd like to get a 128GB card for mine, but the only ones out there at the moment are pretty slow. Even the UHS-1 Sandisk looks like its only ~14-16MB/s. Any idea how this compares to the system storage?

Using A1 SD Bench, I calculated the following write speed in my G3 (D855, 3/32GB):

-> Internal storage: 67.50MB/s
-> UHS1 64GB SD Card (Sandisk Extreme Plus): 27.35MB/s

I suggest you test it for yourself

Thanks! Mine is on pre-order, and I was looking to get a card so I'd have it when the phone arrived. even 15MBps should be sufficient since most phone 4k seems to be in the 6MBps (50 Mbps) range, but I'd hate to get the bigger card and then find out that it's hobbled.
