I have a Crucial SSD that supports their Momentum Cache, which essentially lets me use 4GB of my system RAM as a cache to prevent a lot of unnecessary random writes, and i also enabled 10% overprovisioning beyond the SSDs 12GB standard setting since i have a 1TB drive and can use the OP to increase theoretical endurance.
Any time data is written to, moved around, temporarily cached on an SSD, it counts towards "total bytes written" TBW of the SSD.
NAND flash cells can only be written a finite(but obviously overly pessimistic based on the demonstrated endurance) number of times.
You also have to take into account write amplification, which has to do with how data is written. You could actually end up writing a lot more data to the drive than the file size indicates. Keep in mind that an OS will usually be doing small amounts of reads and writes in the background at all times, and playing a game does a bunch of reads and possibly writes depending on the game and what it decides to page to the SSD.
Heres a good place to start

Well the ssd's are yet to beat the Phoenicians, their clay tablets have lasted over 4000 years. That's good storage without a backup!

Got to hand it to Samsung, their SSD's are plain amazing.
Had a Crucial M4 (remember those?), it died after two years but Crucial were champs in how fast and easy they replaced it. Next drive was an 840 Pro, never looked back.
Right now have an that 840 Pro has been used in an always on streaming and gaming computer for a while, before I retired it and put it in my laptop. Currently has about 13TB written, but nearly 24,000 hours of active time (!), and on the latest tests it's running faster than ever; just amazing.

This is clearly an endurance test and not one for performance, and also, it's an 850 Pro, not the Evo (which had issues already before it was replaced by the following models), as in their decreased read speads because of their firmware.
Still, buying Samsung again, after having had 4 Samsung SSDs in my own rigs, as well as some in rigs I built for friends. OCZ died on me eventually, the M4 is still doing very well.
