About to swap my boot drive for an SSD and after reading various article on SSD life expectancies I'm curious... How should one care for a system running on SSD? Better to put it to sleep, or shut off entirely? Should I allow it to "fall asleep" sooner or later? I've heard that you're not supposed to defrag an SSD, but I'm wondering what else you're supposed to do/not do to maintain a healthy SSD system. Thanks!
