AS-SSD is designed to quickly test the performance of your drives. Currently, the program allows to measure sequential and small 4K read/write speeds as well as 4K file speed at a queue depth of 6. While its primary goal is to accurately test Solid State Drives, it does equally well on all storage mediums it just takes longer to run each test as each test reads or writes 1GB of data.Just as with Crystal DiskMark, the AS-SSD performance results put to bed any idea of this simply being a ‘value’ drive; instead it is a darn good mainstream drive that can even compete against ‘enthusiast grade’ (SATA based) solid state drives. The only way anyone will get noticeably better is by going NVMe (ala Intel 750 series).
