After having to put up with mostly every drive in my system performing incredibly slowly, I decided to check the SMART data for my drives, and according to HD Tune Pro, my SSD is having some serious sector issues.

Some other programs, like Samsung Magician and Speccy, show that the drive is still healthy though.

I'm confused what to think.

The drive performs correctly and passes an error test; However, all other drives in my system are heavily underperforming, as the 'failing' SSD is the OS drive, this would make sense, but it itself performs fine still.

Is the drive failing? Or am I simply reading the SMART data wrong?
