Yes and no, some drives have tripled in price while others have seen modest gains. Checking local stores, I see that the WD Caviar Green 2T drive that used to be on sale for $65 every week is now $180. However, the WD Caviar Green 3T drive that used to be in the $220 range is now... *drumroll* ...$250. Now, I'm pretty sure the 2T drive was significantly less than $180 when it was released several years ago.
It doesn't make a lot of sense to me, but I guess people are still buying the 2T drives instead of the 3T drives, even though the latter actually is ~10% cheaper per gig now.
I have a sneaking suspicion that once drive prices start falling again they'll fall very slowly and may never reach the levels we saw just a few months ago.
