AS SSD is a great free tool designed just for benching Solid State Drives. It performs an array of sequential read and write tests, as well as random read and write tests with sequential access times over a portion of the drive.
AS SSD includes a sub suite of benchmarks with various file pattern algorithms but this is difficult in trying to judge accurate performance figures.
In the AS SSD benchmark, the SSD970 EVO Plus produced a read score of 2133 which gave it an edge over the 2032 scored by the 2TB 970 EVO. However, its write score of 2258 is a little shy of the 2279 scored by the older drive.
