I use the SSD as my boot and app drive on my Poser machine. I use this machine only for my 3D apps and the applications use a separate hard drive to store data (runtimes, project files). I also installed PzDB on this drive which makes it very fast. So there is very little data written to the SSD - my temp file is 5.4GB after 1 year of use and I have never cleaned it. So I probably don't even meet the lowest estimate for an average life time of 5 years, which is a lot better than my HDD drives of 2-3 years.

The speed increase in loading poser, rendering, searching, installing new versions is certainly worth it. And even if I loose the disk, it is just a matter of reinstalling the data on a new SSD - no data is lost since everything is on the (backup-ed) data drives.

But putting volatile data (such as temp files) on a "normal use" machine outside the SSD is probably a wise idea, which I will do on my next "normal use" machine.
