ssd smart fail

Hello,

I have a late 2013 13" MBP Retina. I had windows 7 installed through BootCamp.

Recently i started receiving HDD errors in W7. I restarted and W7 would not load anymore.

I entered MacOS and when i looked at disk utilities i saw that SMART status is failing and that i should backup all data and replace the drive.

So i did manage to backup all the data.

But when i installed "SMART Utility" I saw that the only attribute failing is "Wear leveling count".

After 2 days of reading forums and articles my question is why the threshold for this value is 100? Shouldn't it be 0 (like all other attributes which are good by the way)? Please see attached image below.

What is your opinion of this situation? Can i solve it without buying a new HDD?

Thanks,

Andrew
