Above data are also related to other hardware devices of the computer. If configurations of other hardware are high, then the speed will be faster. But if the configurations are low, the speed will be slower.The actual available capacity of our solid state disk is a little smaller than we listed due to the different calculations between computers and manufacturers.Computer: 1 MB = 1,024 KB. 1 GB = 1,024 MB
