So this christmas I got this micro sd card. Would it be good enough to record in 2.7k with my Phantom 3 standard? Here it is:

It's probably fine.
There's one way to tell  ....

It may or may not, but to save yourself a lot of grief, just buy a Sandisk Extreme series card, they always work.

I agree with Geebax.  
Sandisk Extreme Pro is the absolute most reliable micro SD card out there.  Nobody likes to get a glitchy video when that perfect filming opportunity arrives.  

This cards write speed is below the ones everyone has recommended for drone video recording on multiple sites.  This card is a UHS type 1.  Here's the best explanation I have found about the difference...

UHS came about due to 4K-capable video devices needing faster write speeds. The SD Association has two UHS Speed Classes, UHS Speed Class 1 and UHS Speed Class 3. UHS Speed Class 1 supports a minimum 10MB/s write speed, whereas UHS Speed Class 3 supports at least 30MB/s write speed.

The Extreme series is type 3 but the Extreme Pro is the fastest most reliable. Extreme Plus while not recommended is reasonably price type 3.

Guess whose card generated the card full warning? Then I couldn't delete the videos. After contemplating my navel for a while worked out I had locked the adapter. Hmm it's been a long year.

Being a U1 it's questionable - should of got a U3 to be safe

Been wondering this myself.   The Phantom 4 User Manual states;
Micro SD, Max Capacity: 128GB. Write speed ≥15MB/s, class 10 or UHS- 1 rating required

Does this mean anything higher than UHS-1 is acceptable?  Thanks.
