Not only do you have to pay the huge electric bill to keep those millions of hard drives spinning, you have to have a guy checking and maintaining them, and because hard drives only have a lifespan of about 2 or 3 years, that means all 40 000 000 GB has to be back up almost bi-annually. Thats an enormous effort, not to mention a huge cost
No, hard drives only have to be powered up when they're being accessed. I don't leave my computer on 24/7 and all the data is still on my hard drive when I go back to it the next day. ;-)
Likewise, lifespan is relative to how much use the drive is getting. These things won't be live 100% of the time. It's an archive, not a "video on demand" system.
Also look at the physical space they take up. A stack of film reels is about the size of a large pressure cooker pot. A hard drive - regardless of capacity, is about the size of a pair of DVD boxes.
Backups - that can be automated. You don't have to have someone literally sitting at a computer running backup programs 24/7.
It's do-able, there's just a lot of logistics to work out. As for cost, remember this is Hollywood we're talking about. The only other places with more disposable income are the US gov't and the oil companies.
