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.
With a read score of 2814 and a write score of 3053, the 4TB version of Sabrent’s Rocket 4 Plus isn't as fast as the 2TB version of the drive in the AS SSD benchmark. However, Its write score of 3053 is the second fastest we've seen to date.
