What will be the 3 TB drive size? 2.5 or 3.5?
This is not a repair question, but I really wonder the size of built to order 3 TB drive especially in 21.5". Because 1 TB drive found as 2.5" drive. There is no 3 TB 2.5" drive on the market. It seems, it can't be fitted a 3,5" drive inside. Maybe two thin 1.5 TB 2.5" drives glued :) together? I'm not sure there exists such a single, thin 2,5" drive? I heard WD 2 TB single unit but I'm not sure. I think only ifixit will answer that when they tear down a 3 TB model. Maybe it will be answered by hardware numbers if somebody posts the disk information of such a 3 TB model.
(I edited the question, sorry for the unintentional GB alias for TeraBytes, before.)
