More often than not SMART attributes are completely undocumented and the interpretation of their raw values is a pure guesswork on smartctl devs' part. For your SSD make/model they just have it wrong.
Just FYI for anyone for whom this didn't work by default: I needed to use the --all flag with smartctl (and install smartmontools if you don't have it).
Pro tip: when writing out commands for people to read it helps to use the long form arguments. In this case passing '--all' instead of '-a' to smartctl. It makes it easier to read and more clear what specific options do. Same with calling things in scripts. Short form is for quick and dirty typing things, but not great for reading or comprehension :)
Receiving power isn’t the same as being “on”. I’d assume the drive has a sleep state that it goes into after inactivity, and those hours don’t count as “power on” hours.
Interesting, thanks. The spec does leave it almost uselessly underspecified:
"Power On Hours: Contains the number of power-on hours. This may not include time that the controller was powered and in a non-operational power state."
The same drive reports only 329 "controller busy time" minutes.
960 pro was released in October 2016, even if we assume you purchased it the same month it was released, and you have been running it 24/7 non-stop, that's 50,591 hours counting from October 1st to this hour. I can assume the number is way below 1/3 of that even for people that use it 8 hours a day.
Sounds like you're in the clear for this particular bug...
...but always check your backups regularly for data that is dear to you!
Protip of the day: that includes things on someone else's server. I remember when Grooveshark went offline from one day to the next and I lost nearly my whole library because I remembered only some artists and had to go through thousands of songs to find which ones I actually liked from them. My browser's localStorage object had the playlists but I didn't use those much. Or when 000webhost cancelled my account because I was using the 100MB(?) to back up some files that were most important to me, rather than for actual webhosting (in my defense, I was 15 at the time), and so when I returned from a holiday with my parents with an actual crashed hard drive, that turned double sour. Backing up things from what they now call the "cloud" is something I learned early, as I have virtually no code I wrote before that summer, only some of the music, only essays with WordArt if they were printed, etc.
If you use Telegram, Spotify, Netflix, maybe you have videos uploaded to YouTube and not have local copies anymore... my recommendation is to have backups of things that are important to you, onto a medium that you own (it's only a disaster-case copy anyway), and for copyrighted content like Spotify/Netflix it would simply be enough to just have a list of songs/videos. Maybe Netflix doesn't go offline from one day to the next, but your account might be hacked, or that friend you share it with might be hacked, or the right set of hard disks fail at their datacenter, etc. GDPR data exports are your friend, particularly when they're automated and you don't have to bother support. (They might also reveal, as in my case, that Spotify knows how often you shower because I then connect it to a particular waterproof bluetooth speaker at wakeup time. Data exports are also fun to browse!)
