Have you tried using the Samsung Magician? It may be able to tell you what B3 is.

But any failure is typically a sign that you want to back up ASAP.
Seems like it's "Used Reserved Block Count". Not sure what that is. The software says it's ok though. I'm gonna backup anyway but you think it's a false alarm or not severe? Also should I benchmark?

This parameter is considered informational by the most hardware vendors. Although degradation of this parameter can be an indicator of drive aging and/or potential electromechanical problems, it does not directly indicate imminent drive failure. Regular backup is recommended. Pay closer attention to other parameters and overall drive health.
Always backup but this seems to state its not something to be overly worried about.

I would go by what Samsungs software tells you. If anything you can contact their support and see what they say. I did some searching and found multiple Samsung SSDs coming up with the same information, even some very new, with HD Tune but not with Samsung Magician or Crystal Disk.

Given in hex, so B3 = 179 = used reserved blocks as stated by Redsama. Raw data is 0, current value is 100 (likely the default), threshold is 10, which means the "worst value" of 1 is triggering that program but in reality is likely harmless.
