Vincent, You are directly contradicting yourself. First you state that
disks are "$35 for a 2 TB" and then "3 TB, 200MB/s" disks are €120.
Both these claims are patently bullshit.

Please can you take more care to check your sources and your opinions
when posting. Your posts, although occasionally entertaining,
generally serve to distract the thread into dismissing the hyperbolic
nonsense within. This gets old VERY quickly.
