I dont know where hdsentinel get that figure from. I havent sen anything like it from the manufacturers who only quote tbw as far as I know. You could ask hdsentinel.
Power on time
87.73 TB are a lot of writes for a 256 GB SSD. The TBW spec for such a SSD should be 200 or less, so the actually written TBs are 44% of the rated TBWs. I would replace it ASAP.
According to the samsung site
for the 250gb
Samsung 970 EVO Plus NVMs SSD with V-NAND, 250GB | Samsung UK5-Year Limited Warranty or 150 TBW Limited Warranty
I dont know why there is that apparent discrepancy with hdsentinel.
you could check with diskgenius and post a screenshot like mine to see if there is something odd about the hdsentinel figures.
The real life tbw expectancy is probabaly higher than the minimum guaranteed.
Hd sentinel is doing some calculation based mainly on power on hours vs an average they imagine and then compared to 5 years - which the link I posted earler mentioned.
Just installed DiskGenius and checked out the S.M.A.R.T information. Says 85% for remaining lifetime. Other stats appear good?
It makes me wonder if it really will spontaneously combust in 118 days or not. Now I've learnt a bit more about the cloning process from you guys, I might just go for it, but if there's a possibility Sentinel is wrong then I suppose it reduces the urgency a bit?
Nope. Rated TBWs are just a scam by manufacturers so they do not have to pay out on warranties if a guy goes over tbw in warranty period of warranty. The smart indicator of percent used can actually read up to 256 i.e. much higher TBW than the vendor scam.
As I have repeated many times, a drive can fail for many reasons but write endurance is the least likely reason.
Answer is to make regular backups and replace drive when required.
One could keep a spare blank but as failure could be years away and drives generally increase in capacity for same price, rather pointless unless it is mission critical to have a spare drive. I have dome old spinners that could act as a short term spare.
In the end I went with the Samsung Magician software as it looked the easiest to use.
Clone seemed to finish without a hitch and the system closed down. I then swapped the drives. System booted into my usual Windows set up ok afterwards but it kept freezing whenever I tried to do anything e.g. open a program such as Word or Edge. There was probably a simple explanation for this and it might have been fixable but in the end I just reinstalled Windows.
Be interested to hear if anyone can think of possible causes for the freezing though. Might help if I ever do something like this again.
