💾 512GB Micro SD Card Memory Card with Adapter - High-Speed 100MB/s, Class 10, U1, Full HD Support, A1, 512GB Ultra microSDXC UHS-I Memory Card Review

When I received this SD card (circa March 2016), I knew immediately that it wasn't a U3 card. It was too slow. I kept it anyway as it was still a great price for a 128GB card. (That was lower than the current price at the time of this review.) In any case, it looks like I don't have 128GB either. It seems closer to 32GB according to some reviewers. I've learned my lesson. Whenever you buy a new SD card, test it first (while you can still return it)! The test results are listed below…

Now I can download any of my…

UPDATE: After buying three, one accidentally failed. Even as a photographer who regularly backs up data, there was somehow an error between transferring data from my camera to the SD reader. I do not blame the manufacturer, since there are always marriages in the party. Instead, use my case as an example to remind yourself that 128 gigabytes is very useful but can go down at any time, so backup, backup, backup. This card is AMAZING. Two reasons. That's 128GB at a fantastic price. I didn't have…
