Does write caching cause an SSD to burn up faster? I mean they have a limited life. So disabling it would extend the life of it?
My OS drive has Write Caching, it's about 83% lifespan after 3 years. with 75TB written It's likely something else will fail or you'd trade up before it became an issue.
Write caching is just using RAM as a buffer to reduce the overhead of disk operations. The difference is probably much smaller with SSDs, but it doesn't increase the number of disk writes, so it shouldn't affect the lifespan. If anything, I'd wonder if turning off caching, thus forcing the computer to write every disk operation immediately, would take more of a toll on it.
