Sorry, in France we use TO and GO as you use TB and GB ... Not always easy to write in YOUR language, as you may experiencing the same in wrinting in MINE ...
O stands for Octets, translate in Bytes ... Tera-Octets is equal to Tera-Bytes ... TO/TB .... witch sometimes create differences in meanings, translation error ....
UK say: it is raining cats and dogs
We say: it s raining ropes
Same stuff, different languages.
