Tips: Due to the conversion of 1GB=1024MB, display capacity of a 256GB drive usually appears at around 90% on Windows due to algorithm differences in which 1GB is interpreted as 1024MB on Windows and 1000MB on USB drives. Therefore，256GB SSD drives≈238GB in Windows.MacOS shows the full 256GB .

Note: The Writing Speed remains stable when the file size of each transfer is less than 1/4 of the remaining usable capacity. For example, when the SSD drive has 256GB available capacity left, you can transfer dataless than64GB at a time, and the speed will not drop.
