You always want to look at raw column because for some stupid reason manufacturers like to use their own method of numbering and not all programs will read it correct (though it is better now than it used to be but SSDs are still the wild west). Being zero'd out is pretty hard to mistake, hence why you want to look at the raw for anything other than zeros as it means something has changed. Keep in mind, names and line numbers are also not universal.
So...
Hard drive 101 (some hard drive expert may disagree with some points of this but it's worked for me for years)
There are spare sectors built onto ever disk, when one is used, it's marked as reallocated (line 05). It's not great to use them but also not terrible because they can be used for multiple reasons, so no need to really freak out if you see some reallocated being used but take it as a warning. Also these may not be permanent, sometimes a format can clear them (sometimes) but to my knowledge not if it's your current boot drive, regardless it's when you run out and/or you start to see uncorrected that you need to worry as your drive is approaching death's doorstep. In this case you have 200 to spare and a SMART warning is supposed to trip when it sees 140 being used, IF SMART monitoring is enabled (it isn't always) and IF it decides to notify you (it can put a popup on your screen but more on this in a moment). In this case reallocated is all zeros hence NONE have been used. Perfect.
A sector can also be marked uncorrectable (line C6) without triggering a reallocated number (I think). In this case none is acceptable according to SMART, however I have seen MANY, MANY times where drives will have multiple uncorrectable sectors and never trigger a SMART warning. I have seen entire sections (many many sectors) of a drive failing as I watch and pull a backup of the data and never trigger a warning so while nice don't rely on SMART to warn you of anything. While I would need several extra hands and feet to count all the drives I've caught mid-failure this way, I can count the warnings I've actually seen on one hand. Once again, this drive shows all zeros in the raw column. Perfect.
If you see just one of these, seriously, just one, start backing up data.
Do not think it will fix itself (it won't), do not run a scan to see how many more it can find (oh god!), do not even turn off the computer. Disconnect it from the internet to disable updates (or at least turn off updates), try not to even let it sleep, start backing up data NOW. Not tomorrow, not when you have time, NOW. Stay up late if you have to but do it now, at least get the important stuff. You literally may only get one shot at backing up that data and this may be it. It may die slowly over several months, it could go months without a problem then poof or (and this has been my most common experience) it could go into a cascade failure and wipe out everything as you backup your data. The only thing you know for certain is that it's failing, get your data off of it.
As mentioned the other line to watch is the ultra DMA crc error (line C7), while the SMART data here says the threshold is zero, that's not entirely true. I'm not saying it's good, it means a it misread something or was fed bad data. RF noise, cable crosstalk, quite a few things can trigger this, as mentioned a bad SATA cable is a very common culprit. Point is if you see some numbers here, don't freak, it could simply be a program crashed while writing data, the bummer is you have no idea what data was found to be in error but since it caught it chances are it also re-requested the data. If you see lots or it's increasing try a different Sata cable, if it's low but stable you may never find the cause. This is not a common sign of drive failure but needs to be mentioned because it is a sign of something else usually. Of the few times I have seen the number go crazy, all but two were bad SATA cables, of the two that were not, one had a bad power supply, the other I concluded was the onboard cache had been damaged probably a power surge. Sata cables are cheap and easy to find compared to a new drive. Again, this one shows zero.
I don't think I've ever actually seen a drive with a read error (line 01) or write error (line C8) that didn't also have other more concerning problems.
Far as I can tell this drive is about as healthy as can be, at least as far as SMART data is concerned, just remember it could change at any time and more importantly there is always a chance something not monitored could fail, but as far as smart stats go, this one gets a relatively clean bill of health.
