What's wrong with getting your own server? I'm pretty sure that there was a lot of GPU buying going on when all the other coins came along. But not only GPU's, but also efficient CPU's and mobo's to support lots of GPU's. I hope you're not scared of buying a server..

As far as data centers go, I doubt it. They usually don't stock up large on HDD's, trust me, I've looked at renting high storage servers, they're all either unavailable, or waayy too expensive.

What price?

Also, running huge data center for this is a very big risk because of hard disk failure and reducing life span mining this coin 24/7.

6 months down the road. We will see how many people post their HDD die off here. We will know which brand is the best and worst  

If they can't break even before hard disk eventual dead , they loss huge amount of money

i think HDD mining downside compare to GPU is the hardware turn over rate. HDD turn over rate should be 2 - 3 times higher than GPU. In longer term, HDD mining could be more expensive than GPU mining because of hard ware failure

I put my bet on seagate being able to break even before it die
