Following up next are our usual ATTO read and write tests. ATTO is an often-quoted benchmark because it is easy to use and accurate. For the most part, it is a favorite among reviewers and I have grown to embrace it as much as the next for the last little while. ATTO uses easily compressible data. As manufacturer peak read and write performance ratings are usually achievable using ATTO, whether a device lives up to its marketing claims or not can be validated by this program. Lexar claims the Professional 1800x SDXC UHS-II Gold 256GB's maximum read and maximum write are pinned at 270MB/s and 180MB/s, respectively. The tested results were close to the advertised figures. It peaked at 256.34MB/s read and 185.4MB/s write. Under the curve, its write speed was consistently faster than all the other tested cards. It was marginally slower than the Lexar Professional 1066x SDXC UHS-I Silver 128GB in the read section up to 32K, but the difference was very minimal. Overall, the Lexar Professional 1800x SDXC UHS-II Gold 256GB's performance was excellent compared to other SDXC cards.
