Hi,
Please see:
32gb evo + can theoretically gain 20 MB/s write and 95 MB/s read speeds
Samsung rate the write speed as “Upto” on EVO. Not guaranteed.
And with read and write speeds of up to 80 MB/s and 20 MB/s respectively,

I personally use Sandisk Extreme UHS-3 range, with higher write speeds. With SD overclock (link above), 26-37.5MB/s write.
Up to 60/40 MB/s read/write speeds for faster recording and transfer

Rule of thumb, Upto does not mean you’ll achieve it, so purchase an SD card with a higher write speed than you need to avoid disappointment.
