This is probably a 'normal' value. The problem is that no one, except Samsung, knows what this means.
Very few SMART attributes are standardized. A lot are proprietary. In particular, SMART attribute B5 (181) is neither defined officially nor de facto. As a result, it has no user accessible meaning.
However, one thing can be pretty certain - it definitely does NOT mean that your drive is having flash programming failures, because it isn't an SSD. Flash program fail is an SSD specific error, and indicates that the a flash chip has a bad sector. It's unclear where the smartmontools project got this definition from - but it is was probably from an obscure SSD supplier that uses it on their drives.
Second, the SMART 'raw' value is not designed to be human readable. What is more useful is the 'value' (in this case 100%. This is designed to be human readable in the form 100= optimal. Lower = worse. The fact that even though the 'raw' value is going up, the 'value' is staying at 100% suggests that the drive isn't bothered about whatever B5 means, but it's just logging it for information.
