The Samsung EVO card is one of Samsung’s slowest cards. It’s also a fairly old card as the new models of the EVO cards put out some decent performance.
I wouldn’t buy this card since there are so many better options out there at great prices with superior performance. I would even take the Sandisk Ultra card over this one.

Real World Memory Card Performance
In real world memory card performance, this card is pretty bad. It performs about the same as the Sandisk Ultra with in-camera tests but it’s USB 3.0 read and write speeds are significantly slower than the Ultra card when tested in the best uhs-II USB 3.0 memory card readers.
