Samsung 850 EVO 120GB: How much bytes written is normal?

After roughly 2 months, I finally got around to installing Samsung's Magician software. When I opened it however, I was quite surprised to see that in about 2 months of use, I'd wriiten 0.48TB of data!

I haven't been mindful about using my HDD for storage, however I'd like to know if this is average
usage for an SSD since this drive has to last me another 2-3 years. I've already enabled Over provisioning and the Maximum Reliability profile in OS optimization of the Magician software, but are there any other steps I can take to extend the life of the SSD? And roughly how many bytes can be written to it in it's entire lifespan?
 
The Samsung 850 EVO warranty provisions for 5 years OR 75TB of written data. If you average .25 TB of written data a month, that makes 3TB a year, and 15TB over 5 years. You would have to write a WHOLE lot more data than that to make the warranty expire before the 5 years is up.
