Only 250 Billion bytes instead of the advertised 256 billion in Sandisk Dual Drive

Purchased this disk (256GB). Turned out to be only 250,148,270,080 bytes instead of the 256,000,000,000 bytes that I should have gotten. Also checked thru properties of the drive thru disk management but the no of bytes were almost the same. Did I get scammed by Sandisk? (Official drive btw)

Yes, it’s dishonest marketing that should be punished by the regulator.
