Since the shortage of hdd's is now supposed to last up to 2 years, the one's still available have become as costly as ssd's. I had to buy a new hdd last week and it cost almost $200 for a 2TB SATA drive. No, not SATA 2 or 3. SATA 1, if there ever was such a thing. It wasn't even OEM, it actually came in a retail box. The WD RE4 2TB drive I wanted costs over $350 now. 2 or 3 weeks ago it was closer to $200.
I think more people will choose ssd'd over hdd's for now and this may help drive the prices of ssd's down to a more reasonable level. I doubt that this will be the end of hdd's because of their massive storage, but I also bought another Crucial M4 256GB ssd last week, too. It turns out that it cost exactly the same as the hdd I actually wanted. The 1st 2 of these ssd's I bought earlier this year were just over $400 each. The prices of ssd'd are coming down while the price of hdd's have skyrocketed.
