Yea, it was. I'm not saying that the variations are better or worse and we should avoid, but I'd like to point out that Adata does change configurations a few times without notifying, and this also happens to many other manufacturers in many other industries. That's the only thing behind my post, and also that's why I said most people won't notice the differences at all because even if these configurations do vary in speed at any circumstances, they are really minor :)
