The Delkin V90 UHS-II 280MB/s card has always been a solid card and a great bang for the buck. This particular model is rated at V90 Video Speed Class. This means the card is guaranteed to put out a minimum write speed of 90MB/s.
While the Delkin memory card doesn’t always perform as quick some of the other brands when it comes to USB 3.0 read and write speeds, it does deliver on in-camera speeds and is often faster than even some of the best cards from Sandisk and Lexar. This makes the Delkin card a great choice for UHS-II shooters.
Delkin V90 UHS-II Memory Card Sizes
The the Delkin V90 UHS-II card is available in two sizes – 64GB, and 128GB. There are however two other sizes available at 16GB and 32GB that match the 280MB/s and 250MB/s read and write speeds, but they are SDHC (32bit) and are not rated at V90.
I recommend check both BHphoto and Amazon prices as they can be significantly different.
