Answer 1

In my knowledge, facebook has no less than thirty thousand servers there with them and expanding, so big data, big requirements and expenditure.

The best way to store those in my view is to simply upload photos and videos to specific folders and simply save the file names in the corresponding tables rather than photos and videos themselves in blob format.

Best get it straight from the horse's mouth:

Given that the flickr presentation is quite dated (still talks about PHP4), you'll probably want to check out the flickr developers' blog, which has a ton of inside baseball on developing high scalability applications with large data storage needs: http://code.flickr.com/blog/2010/02/
