Review on Transcend 128GB SDXC Class 10 UHS-1 Flash 💾 Memory Card - High-Speed Data Transfer up to 90MB/s (TS128GSDXC10U1) by Matt Reid

After using H2TESTW (free SD/USB tester - google it) to test the capacity and speed of the card, I can say that it is indeed a 32GB card and not fake. But 90MB/s? Do not make me laugh. The maximum write speed is 21.3MB/s, and when using an SD card in the camera, the write speed is crucial. The fastest I could read from the card was 56.1 MB/s - not bad at all. Great when copying photos/videos from a card to a computer. However, still nowhere near 90 MB/s. Because it can only write at 21MB/s, it's still a U1 card, not a U3 card. According to the specs on Wikipedia, the U3 can write at over 30MB/s. I'm not entirely happy with this card - 21MB/s isn't too bad - it captures 1080p video quite well. The only thing I don't agree with is that it says "90MB/s" on the front of the label.
