At least in the USA, bare 2TB drives are $120. 2 years ago I spent the same $120 on a 500 gig drive.
I have seen 1.5TB drives for $70 after rebate.
Wow...I bought a 500GB WD drive 2 years ago also and paid almost $150. I can't believe that now I could get 2TB for the same price...
10 years from now, we'll be joking about how small a 3TB drive is and how we can't imagine how we got along with something that small as WD announces its 40TB drive!
10 years from now hard drive will be a joke, everything will be SSD or something other flash technology. In few years, we'll have SSDs that are over 1TB and smaller than stamps...
I remember when I bought my Macbook with an 80 GB hard drive; I remember thinking that there was no way in he!! I'd ever have enough of anything to fill up a vast 80 GB. How times have changed.
But 10 years from now 1TB will never be able to handle our storage needs. Heck, files keep getting larger...we will all have super HD video files on our drives in the future that probably take up a minimum of 25GB by 2020.
I would think each computer will ship with a minimum of 8TB of storage.
Unless there is some MAJOR breakthough in SSD technology, multi-platter, spinning-disk hard drives will still be with us.
The only thing that may change things is if households can be 'wired' with firbe optic lines and then we would have such a HUGE data pipeline that most of our info could be stored in the 'cloud' and accessed instantaneously.
How many SSDs size of a stamp you can fit in 2.5" SSD? Hundreds, even thousands.
