Legitimate 256 GB card, working nicely

I ran a H2testW read/write test on it, and confirmed it is a legitimate card and not counterfeit. For those who don't know, that's a program which writes test files on the card to fill up the memory and test that the card truly has the full internal storage capacity that it claims to, because counterfeit cards exist which are designed to appear to have a given storage capacity, when in reality the actual capacity is much smaller, which causes files to overwrite eachother and corrupt. Anyway, this card passed, it's a proper 256 GB card. The limitations of the connector i used prevented me from testing the Express read/write speeds, so I can't confirm that aspect, but the memory is good and I am using it now happily.

Super fast chip!

I went with the microSD ship that was the less expensive option. I'm shooting 4K video with my drone and I wanted to be able to record onto this microSD without problems. This ship cleaned. It would do 4K video at 30 frames per second but after getting it and installing it, it will record a 4K video at 60 frames per second without a problem so I am super happy with this purchase. I'd recommend this product to anyone who is doing anything with UHD video or otherwise.
