why take the chance anyway? the speed increase in the boot time is small (it still needs to load the data from the ssd back in memory). instead give s3 sleep a chance (bios - sleep mode s3) and start run cmd - powercfg -h off and then try the sleep command.
s3 sleep is all components off except for ram. it loads back instantly and nothing is written to the ssd.
Mainly because a Win 8 shutdown/start re-initializes all drivers. That is not the case with S3... where basically the system may go weeks or more before Win updates force a restart. In my opinion (and you know what they say about opinions) going for long stretches (days and weeks) without a system restart can be unhealthy for the system.
As for "why take a chance?"... I guess the point of my post was to just confirm that my math on SSD write durability was sound. If so 73 years, or 50 years, or even 25 years durability of an SSD to me seems to be taking no chances, but am trying to validate I am evaluating the subject correctly, not trying to eek out an extra 5 seconds of start up performance.
