Yep, got the shaft on that card. Tested the speed. 5.5 Lbs. Tested a different card I have 10.8MBs. Got it on eBay and the seller is no longer active. So I guess I'm stuck with it.
I had a slow class 4 sd card to start out with. Says slow card. I get this new card, and still same....slow card warning. Formatted it, restarted all, drone, controller and app. Any ideas? This card is rated write speeds up to 90 .
