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.
The KC400 512GB scores very highly in the AS SSD test, with the second highest read score our of our tested drives. But more impressive still is the write score of 505, the highest in this capacity segment we have seen to date.
