I'm running some 50 servers with ext4 each server has 2x15TB ext4 partitions. 
I haven't had an issue with that setup. The first server was setup 3 years ago. 
It is quite faster then XFS in terms of write performance and thus far 
reliable without any major problem.

Keep in mind that user land tools are limited and the biggest partition you 
can create with them at the moment is 16TB. You can recompile the tools and 
remove this limitation if that is a problem for you.
