I've had this disc for a few months now. This is the 64GB version and to date I have never filled a drive to capacity. The formatted capacity is 58.5GB, and the drive just doesn't write more than 29.8GB, meaning the drive is half the advertised capacity. Also, the drive never transferred faster than 26MB/s, so the advertised speed is also a lie. If you need a drive that performs the way it's supposed to, look elsewhere because this will quickly become e-waste.
