Is it time to panic? (SSD wear leveling)

[da na]

Checked one of my SSDs yesterday and to my surprise I saw its wear leveling count value was at 14.

Now, does this mean there's 14% "good drive" left or that I've "used" 14% of it with still 86% to go? Its life is still at 100%. 
The datasheet doesn't say how many GB written it's rated for from what I can find. However it does say

So I believe my drive is still 86% usable but wanted to make sure. I'd assume it's rated for 100tb and I've used 14% of it as I've written 14 TB or so as HWiNFO says, is that correct?

Drive is an SHFS31-1000GS-2. Used for a little over a year.

Now it's lived most of its life in under temperature, could that be damaging it? The case keeps it too cool. Should I find a way to heat it up? 

Thanks in advance.

relax you should have a long way to go. i have a 60% ssd and it still working fine.

with ssd, keep out all your important files, have windows historically backup your documents.

ssd working temperature should be around 40-80c for best lifespan.

one way to keep it hot probably to isolate the heat with something like a rubber wrap, just an idea i don't know if it would work.

The temperature is related to data storage longevity rather than actual damage.  The hotter it is when writing, the longer the data will remain stable.

 

The frustrating thing is the cooler the controller is, the faster read/writes will be.  So its a balance between data integrity and speed.
