Bests & Worsts Reviews from Amazon

This card has performed well in testing, both in my PC and in a Samsung Galaxy S8+. I have compared it to two other popular cards so you may make a determination based on your needs. The cards tested are a - Samsung 128GB EVO Select - SanDisk 64GB Extreme Pro - SanDisk 128GB Ultra Testing equipment - Samsung SM-G955U (Galaxy S8+) using A1 SD Bench - Kingston FCR-HS3 card reader via USB3 port using CrystalDiskMark 5.2.1 x64 (UWP) The Samsung 128GB EVO Select and SanDisk 64GB Extreme Pro performed comparably at the PC with the SanDisk 128GB Ultra dropping 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 write On the Galaxy S8+ the speeds really spread out. The SanDisk won for read speed here, but the 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 write For the mobile platform or basic needs, the Samsung is the clear winner here. At a competitive price and with performance above the competition, I highly recommend this card.
