May I ask, why are you using "Gio" instead of "GB" for "gigabyte"?
Based in Europe france and we are saying / using the word giga octet to indicate a hard drive storage capacity which is in English equivalent of giga byte. 1Go or 1Gio = 1GB or 1GiB to simplify.
Below an explanation from wikipedia about why using the I in expressing a storage capacity.
The notation 1 GB represents 1,000,000,000 bytes or, in deprecated usage, 1,073,741,824 (230) bytes. Per IEC 60027-2 A.2 and ISO/IEC 80000 standards, the correct notation of 230 is gibi (symbol Gi).[13] One gibibyte(1 GiB) is 1,073,741,824 bytes or 1.074 GB. Despite international standards, the use of 1 GB = 230 B is widespread. A laptop advertised as having 8 GB has 8,589,934,592 bytes of memory: 8.59×109 B, or 8 GiB.
