You can size it like the following

2000 users
100 messages a day
Total = 200,000 message a day
Messages per year = 400 * 200,000 = 80,000,000

Why 400? Because precision is not needed. All of the numbers are just guesses to give a goal.

Then further what is the average message size? 100 bytes or 1,000,000. Obviously the second is going to be because they are transferring files and not just messages. So do you keep the files also.

One thing I don't see in your post is growth rate. Are you starting with 200 users and only expect them to grow to 2000? Or the market that you are targeting, at best, only has about 2000 users?

You also do not document retention rates. How long do you keep the messages? 1 year? 7 years (often sufficient for most legal/business reasons)? 20 years?

So what database do you need? Any really. Nothing you posted suggests a need for 'speed'. All you are doing is keeping it for future analysis. You could even just write it to files.

You also do not mention personal security. Presumably, excluding the analysis, the messages are not subject to random poking around by operations personnel so how do you secure that?
