200tb is little, depending on your constraints you can even fit it on a hard drive array within your office. There are so many options, if you would list your requirements, constraints or the problem you're trying to solve exactly, that would help come up with a proper advice.

We are expecting the amount of data to at least double every year for the next couple of years. That would mean that in 5 years, we'd have to manage more than 500 16 TiB hard drives in our office :D

We don't really have that many constraints, despite that it should be cost efficient and save us from loosing all our data.
