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. It uses
incompressible data samples, which many drives struggle with, so results can be viewed as the worst case scenarios.
AS SSD includes a sub-suite of benchmarks with various file pattern algorithms, but this is difficult in trying to judge accurate performance figures.
The Kioxia Exceria Plus G4 sits below the other two drives using the Phison PS5031-E31T, the reference Phison E31T design and Corsair's Corsair MP700 Elite with Heatsink.
