Also keep in mind that 1.5 and 2TB drives that are out right now are
all consumer grade drives, built to be put into a workstation singly
or maybe in pairs. It's much less common to see such a change in
server class drives, because the manufacturers know where they'll be
used, and also because the server grade drives usually piggy back on
the workstation class drives for a lot of their tech and bios, so the
need for sudden changes are less common.
