We are going to digress from our tradition of comparing hard disk drives of the same capacity within a single review. Not long ago we wrote about 1-terabyte and then about 2-terabyte HDDs, so we already know HDDs of these capacities well enough. But as is often the case, soon after those reviews we came across a number of interesting products. They are too few, however, for us to write two independent reviews, but we do want to tell you about them. That’s why there are both 1- and 2-terabyte HDDs in this article.
