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.
Due to its small size and small onboard pseudo-SLC write cache buffer the MX300 275GB is decent but only decent in single drive configuration. It really is not until you opt for four of these wee beasties does our opinion change… and boy does it change!
