Last time I checked it was 5x8 $ = 40$
But as it is fast and definitely not throttled, I really love their service.
I uploaded for testing 12.8 Terabyte just to test, if they really mean it. They announced a file size limit of 5 TB. So I tested it and it worked.
The file is still there.
Amazon CloudDrive and Microsofts one Drive Business are hilarious. They throttle or loose files. I really do not understand why google drive was not implemented in the Beta.
