Bests & Worsts Reviews from Amazon

***Second Purchase (FAKE Card) - May 2018*** As you can see below, I purchased the first card from this same listing on Amazon and it was real. Unfortunately a year later I purchased the same card from the same listing and now I received a fake. I noticed the box had some hard to read print on the back, but didn't think much of it. Then upon opening the card I noticed that the locking tab was yellow, not grey like my first one. Upon even closer inspection, I noticed that the new (fake) card didn't have a batch/serial number on the back, and was missing the "Made in China" engraving. Once formatting in my camera and testing, I noticed that the card easily took 10 times as long to write a photo to. Also, the camera was saying that the new card had a higher capacity. As I am using these cards in a Sony A7Riii, and the fact that it takes 100MB 43MP photos, I require high speed cards, hence why I purchased the fastest UHS-I card Sandisk makes. Amazon in the past has provided real cards, but in this case it was fake! To the untrained eye or average consumer, most will not notice this until they have VERY poor performance from the card, and may think it's their camera, device, etc. See below for test and comparison photos. ***Original (Real Card) - June 2017*** I used this card in my Sony A6500 for about 8 months shooting about 20,000 RAW images without a single issue. I've now upgraded to the Sony A7Riii and am getting great read/write speeds in-camera with it. As some may know, the camera has 2 card slots: one UHS-1 and the other UHS-2. UHS-2 supports triple the speeds over UHS-1, which is what this card is. I still get more than acceptable burst rates before the buffer fills. I see no reason to ugprade to the twice the price, half the size UHS-2 cards for this camera.
