I was looking at the Hitachi 2TB and 3TB 7200rpm Deskstar hard drives this past summer and I remember the prices on Amazon being around $110-120 for the 2TB and $160-170 for the 3TB drive. I didn't buy them at the time, but am now in the market again. So, much to my surprise I looked on Amazon and now the prices are $205-220 for the 2TB and $330 for the 3TB. WHAT HAPPENED!? I kinda thought prices for HD generally went down not up, and certainly not double in price. Anyone know why?
