Depending on your usage, this can prove to be a big negative. If you need a key to large capacity to regularly transfer large volumes you turn instead to a superior range, faster, if speed is important to you.
As convention for all storage formats, we speak of capacity in GB 1000 MB (instead of 1024), count 7% less in capacity level in practice (this is NOT a fault is a matter of conventions).
Update: Repetition crashes when files are too large (file GoPro), very very slow (3 MB / s).
Trash. A star because you can not put 0.
