Micro SD question

[WokeUp]

Hey guys I bought a phantom 4 and it came with a 16GB sd card the drone can record in 4k the SD it brought is a Lexar 633x I have a 64GB SanDisk Extreme Plus Micro SD for my gopro and a 200GB sandisk SD for my phone can they all hold 4k or only some Micro SDs? basically what Im asking is if I need a specific Micro SD for 4k..

@MartinWake You'll need a MicroSD that'll have high enough write speeds to write the data fast enough. 4K 30 FPS is about 40 Mb/s (~5 MB/s) and 4K 60 FPS is about 65 Mb/s (~8 MB/s).

By the way, those bitrates are lossy compression (i.e. h.264/ AC).

It gets even better with RAW files, which would be (12 bits per pixel x Resolution x FPS)
4K 30 FPS = 12 x 3840 x 2160 x 30
                  = ~2847 Mb/s (~356 MB/s)

4K 60 FPS = 12 x 3840 x 2150 x 60

                  = ~5695 Mb/s (~712 MB/s)

I was just giving some fun facts . A 4K image would be about 8.3 MB, but a 4K RAW image can vary anywhere in between 10 to 17 MB.
