Yes, but less consistency safe.

It depends :-)

I think the idea with cassandra is that it scales linearly. So, if you have 
obtained some performance numbers X for read performance. And you get lots of 
new users and data amounts, you can keep having X simply by adding new nodes.

But I think there are others on this list with much more insight into this than 
mine!
