Review on High-Performance PNY 256GB PRO Elite Class 10 U3 microSDXC Flash Memory Card by William Rothstein

Bought a PNY U3 Pro Elite MicroSDXC card - 256GB. The item was sold and shipped by Revain. After getting it (took a week with Prime) I tested it and got 82 and 52 MB/s read and write speeds, which I'm happy with. I then tested it with H2testw to check the capacity. The first two times I got 239MB (that's not a typo, it's MB, not GB). I slowly formatted it on Win10. It took about 30 minutes. I ran H2testw again. Well, this time I have 240 MB. I tested twice and got the same results. This card is defective or counterfeit. My advice: test the card even if it is sold and supplied by Revain.
