What is the TBW on a SK Hynix BC501 HFM256GDJTNG-8310A

I updated Windows earlier today and got an error on the reboot, saying that my SSD drive failed the S.M.A.R.T. test.  I was able to boot the computer and in fact I'm using it now.  In researching the situation, there is only one issue that I've found and that is that my remaining life on the SSD drive is 3%.  I've only had this computer for a little over 2 years (28 months to be exact) and from the diagnostics I've run, I've written a total of 20.345 TB to the drive.  That seems an extremely low number to have only 3% left on my SSD.  I was expecting to get somewhere around 100 TBW out of this thing.  Anybody know what the TBW is on this particular SSD?  I shouldn't have to replace my hard drive, or computer after only 2 years.

TBW is for terabytes written which is how much you can write cumulatively into the drive over its lifetime.

I know what TBW stands for.  Sorry, if I wasn't clear.  My question is how many TBW should I be getting from this SK Hynix SSD 256 GB.  I know a Samsung is rated for 150 TBW at that size.  While I didn't expect that much from it, I certainly expected more than 20.345 TBW.  Anybody know what this SSD is rated for as far as TBW?  The answer will be a number.
