one of the things that bug me and makes me want to make my own youtube channel is this rubber stamp answer
that says ssd is the best thing you can have.
SSD is like a ram disk with a very long erase cycle. if you unplug your computer and put it in storage from 3 months to a year your hard disk WILL BE ERASED. its very important that you still run time machine..
this is what dell says back in 2011
SLC 6 months
eMLC 3 months
MLC 3 moths
here is a link that said the maximum time someones data was left alive on a ssd was 18 months

that page is only six months old
anandtech says its nothing to worry about and it will take 10 years of heavy use before you have to worry about
what will happen to your data after you turn it off, peoples opinions are different. but i would make sure
that you keep using time machine.
unplugging i think is required for the SSD to be erased. if you simply just turn it off but keep it plugged in, then
the zombie power feeding your smc controller might be just enough to keep the drive alive. as far as MacBooks go, i think your data is safe as long as the battery is physically connected to your logic board and the battery does not reach 0. whenever a macbook has some kind of power source, something is keeping the contents of your smc ram alive, and maybe thats good enough.
i think this would be a good story. pram is nvram, smc is just ram
another one of my pet peeves are hybrid hard disks, like the seagate st500lm000 , people like me, duh, put them in usb 2 cases when the drive is not rated for usb 2 current. and it causes the them to panic and refuse to spin and they start beeping , it sounds like crickets.
