This is not nearly as good as my Sandisk Extreme 160MB/s compact flash card which is able to take 32 total frames over the course of about 6 seconds; if you do a lot of action photography on a camera that doesn't have UHS-II support, like the D810, you'll want to spring for a good compact flash in place of this SD card

Very good flash memory for my camcorder

Its a flash card and it works as a flash card should.
