PNY 256GB SDXC class 10, 256 GB, SDXC, Klasse 10, UHS-I, 100 MB/s, 75 MB/s

This provides good performance, but it is not as fast as other U3 class cards that I own. The price I paid made this a good value, and the 128GB size allows me to capture a lot of video without having to swap out cards.

The reviews that gave 1 - 2 stars are right. We ordered this MC because it claim to have an 'elite performance' but after a few months of using it, it just stopped working. I got Try another SD card error. I also tried to mount it on PC and it can't be detected. A lot of important footage were lost.

Ordered 2 PNY SD cards, One DOA The other one worked for a bit then bricked less than 2 weeks later. Will never buy PNY SD again.

If you fear the the single card slot this card is the one you want. This is my second PNY card and I have never had one fail on me yet. For the price this card is brilliant!

I have had this card for 2 years now using exclusively as a video library drive for my MacBook Pro. Has performed flawlessly for me and still works fine.
