I wouldn't worry too much about write endurance with modern SSDs - at least if you're not using them in a server or something. The Samsung 850 EVO (not even the PRO model) is rated for 150TB, and most tests got closer to double or triple that number before the drive failed.
If the full contents of a 16GB memory are written to disk for hibernation daily, with say another 50GB of work, that's over 6 years before you hit the lower limit. I probably wouldn't trust a hard disk that was used that heavily for that long either.
I've written 40TB so far to the 1TB 850 Evo in my workstation and it certainly has problems now that it didn't have before - it just hangs for a few seconds at a time, when copying or deleting large number of files. Not sure what it's doing.
If by chance it's an 840 (rather than the VNAND 850), there's been two firmware updates to improve performance over time - make sure to update the firmware.
