Keep getting write errors in HA - not sure if its because HA logs all sorts of ****, or because my SSD is dying.

Correct, but google how this parameter should be interpreted on your SSD model/make. It is not tripping parameter even if it drops to zero, so is not considered a critical. All others parameters indicate no wearing, no errors, no firmware lockups.

Thanks - I have no clue what drive it is - but I recall seeing it in the above output, so will have a look again.
 
According to smartctl:

  • Wear_Leveling_Count — Stands for the remaining endurance of the drive in percentage (starting from 100 and decreasing linearly as the drive is written to).
So it may well be that your drive is on it's last legs.

Make, model and age if I may ask? I have an OCZ Agility 3 running my HTPC from 2011 that is still chugging along so I am curious to see if I should be expecting a replacement in the near future

Samsung 750 EVO SSD - 120GB - bought - 4 March 2016

So just under 3 years old.
 
Now I need to order a replacement ASAP - copy what I can - and return to takealot.

EDIT 1: 3 years or 35 TBW (TOTAL BYTES WRITTEN ) - how do you find the TBW? (I'm assuming it's not 35 bytes)

EDIT 2: Out of Samsung's Warranty page - other sites list TBW as Terabytes Written - which is probably more accurate

EDIT 3: Seems you use Total_LBAs_Written - which puts me at 23.23 TB - so within 35.

Quickest for you would probably be to stick it into a Windows machine (Or Linux with Wine) and run Samsung Magician software which should give you those stats.
 
I actually think it might not be worth the hassle - they're probably going to come back and say the drive has 8% of life left, which will surpass 04 March - and I won't be able to prove write errors. The equivalent drive size is also only R450 odd now.
 
Personally, I would just get a new drive, then use this one for a second drive. Like for swap space or something. Havent heard of any "recent" drives dieing.

I also dont think they even make the 750 range anymore. I have the 500GB version and dont see it for sale anymore.

Out of curiosity I checked my work machine and found that it too had lacklustre lifetime for some odd reason:

SK Hynix SC308 m.2 256GB
Power-on hours: 13283 (553 days)
Power cycle count: 253
TBW: 13 059 GB
Life Remaining: 28%

My home drives below for refence:

OCZ Agility 3 60GB 2.5"
Power-on hours: 20765 (865 days)
Power cycle count: 842
TBW: 9624 GB
Life remaining: 97%

Samsung 850 Evo 2.5"
Power-on hours: 6720 (280 days)
Power cycle count: 650
TBW: 10 500 GB
Life remaining: 98%
