The Samsung EVO series represents the middle choice in the new-for-2014 Samsung SD memory card line. The EVO is touted for its "Ultra-fast Performance," however it is not the fastest card from Samsung, that attribute is reserved for the Samsung PRO SD card. The EVO sits between the PRO and Standard cards.
The EVO features a white plastic case with bright orange and grey printing. It is available in 16 and 32 GB capacities. It supports UHS-I transfer protocol and is rated as Class 10. Its transfer speed is advertised as up to 48 MB/s, however no number is given for write speed which we found to be significantly lower.
The EVO series uses Samsung NAND flash Triple Level Cell (TLC) memory flash which stores eight bits of data per cell. TLC costs less to manufacture compared with MLC or SLC memory because it requiress less silicon. Samsung is the largest NAND flash memory producer in the world and in May 2014 opened a new $7 billion NAND flash memory factory in Xi'an, China.
Benchmark testing was performed in eight different USB 3.0 SD card readers. Sequential reads averaged 47MB/s maximum and sequential writes averaged 28MB/s maximum. In benchmarks it revealed an interesting benefit. It has relatively high random write speed up to 24MB/s. For photographers this is of little benefit. Small random writes are beneficial for applications in computing were small files or pieces of files are read and written such as when running a program. In photography relatively large files are written sequentially.

In addition to several benchmarks, we tested the Samsung EVO in many different digital cameras. Here we found it offers moderate performance at best. It fell well short of other UHS-I SD cards and ended up being the slowest card by a significant margin. In most cameras this card only performed at 16 to 18 MB/s write speed. Its highest write speed (21.9MB/s) was measured in the Canon 7D Mark II. While the Samsung EVO rates above Class 10 performance (10MB/s write minimum) it is far from the "Ultra-fast Performance" implied on the packaging.
