What type SD card should I use for both camera and st16?

I have a red one that is being used in the camera and a black one that's being used on st16, but sometime video comes out freezes a little could this be because of the sd card.

The Adata card is much to high in capacity for the ST-16. The -16 does not like to recognize capacities higher than 32g. There is really no reason to keep a card in the -16 as everything, including telemetry is saved to system files for later downloading if desired. The video stored in the -16 is auto degraded to 720p quality, is constantly over written, and not auto stored on the card. Nothing is auto stored to the card. The purpose of -16 video/image files is for general review of what you just shot in case you want to do it over. The only video you want to save is what is on the camera card.

The only card you need for the -16 is the 16g card that came with the system, which should be set aside and saved for use with firmware upgrades.

I use Samsung SD Adapter for micro SD 32GB. Never any issues.

Also, the 128 gig Sandisk card is only a class 10 - U1 and is not fast enough to write 4K video, so essentially its only good enough to do 1080. To record 4K, you'll need at least a U-3 card.
Here is one on Amazon that will do the job. U-3 SD CARD

Walmart has 32 gig U3 sans disk cards for around 29.00$
