This card performed well in testing on both my PC and the Samsung Galaxy S8+. I've compared it to two other popular cards so you can draw your own conclusions based on your needs. Cards tested: A1 SD Bench - Kingston FCR-HS3 card reader via USB3 with CrystalDiskMark 5.2.1 x64 (UWP) Samsung 128GB EVO Select and SanDisk 64GB Extreme Pro showed comparable results on PC, SanDisk 128GB Ultra lags behind in write speed. - Samsung 128GB EVO Select 93MB/s read and 80MB/s write - SanDisk 64GB Extreme Pro 93MB/s read and 82MB/s write - SanDisk 128GB Ultra 90MB/s read and 17MB/s for Writing on the Galaxy S8+, speeds are really spread out. SanDisk won here in read speeds, but Samsung clearly beat them in write speeds. - Samsung 128GB EVO Select 59MB/s read and 40MB/s write - SanDisk 64GB Extreme Pro 22MB/s read and 8MB/s write - SanDisk 128GB Ultra 66MB/s read and 16MB/s for Writing is the clear winner here. I would highly recommend this card for its competitive price and performance above the competition.
