I've been shopping, recently, and while I'm not looking in that size range, the prices in that range that I've happened to notice align with what you're saying, the the extent I recall. (For me, in the U.S.)

The exception, I guess, might be for extremely fast platter drives or for SSD's. (And with platter drives, you're still to some extent up against speed by virtue of rotation speed versus speed by virtue of data density.)
