Crystal Disk Mark 8.0 is in the spotlight. Just a bit of background information, higher capacity devices tend to perform a little better in these tests. The ability of a controller and flash memory to deliver high IOPS will provide huge benefits to the score as well. Looking at the read and write results of all four sections, the Lexar Professional 1800x SDXC UHS-II Gold 256GB dominated the sequential Q8T1 read and write section against the compared SDXC cards and virtually matched the advertised figures. It also dominated the Seq1M Q1T1 read and write test. Other SDXC cards got closer in the RND4K Q32T1 and RND4K Q1T1 segments, where the Lexar Professional 1066x SDXC UHS-I Silver 128GB actually beat the UHS-II Gold card we are testing today in the RND4K Q32T1 read test, but only by a very small margin. The Lexar Professional 1800x SDXC UHS-II Gold 256GB was simply untouchable in its write speed. I will let you make your own comparisons in our list of SDXC cards in the graphs above.
