Samsung 850 Pro SSD Reaches End of Life With 9100 TB Written
No, that isn't a major typo on this article's headline. According to print magazine c't, who conducted a test bench consisting of two pieces each of OCZ's TR150, Crucial's BX 200, Samsung's 750 Evo, Samsung's 850 Pro, SanDisk's Extreme Pro and SanDisk's Ultra II, the last SSD to actually give out the last breath was Samsung's 256 GB 850 Pro, with a staggering 9100 TB (that's 9.1 Petabytes) written. This is well beyond Samsung's suggested longevity for this particular SSD, which stands at 150 TBW.
The first particular model to give out was one of Crucial's BX 200, at 187 TBW (still more than twice over the manufacturer's 80 TBW). The second model to fail was the second Crucial BX 200, at 280 TBW. The remaining SSDs apparently died after a power peak (unclear whether a surge or a spike), save for the Pro models, in the form of SanDisk's Extreme Pro and Samsung's 850 Pro (it seems those Pro-oriented features do serve some purpose, eh?.) One of these SanDisk Extreme Pro models lasted for about 2,200 TBW, the same amount of writes the first Samsung 850 Pro model endured. However, the second Samsung 850 Pro broke through all records with its total 9,100 TB written. Naturally, these are interesting and impressive overall results, but they can't really be counted upon as being statistically significant; two models each aren't enough to achieve a representation of the tested SSD models' endurance. However, this also probably means that save a defect on your SSD's manufacturing, you can count on it for a considerable amount of writes.

As for Samsung that is seriously impressive. I am saving up for a 960Pro 1TB NvME drive next.
I pulled it from my system just 2 days ago to consolidate my storage (I'm barely using 200GB on my newer 512GB Sandisk X400). The old drive will probably move to my laptop.
C't Magazine - How long do SSDs really last? - March 17, 2017
HDDs are starting to be advertised with a TBW number to put them in perspective. It's mostly the warranty length x the maximum sequential write speed but it can be used the same way as a write endurance from SSDs.
Seriously that is some impressive numbers and alot of data.
While hdd litterly failing around me (3 just this year so far. 1 external and two wd velociraptors alright those raptors where 8 years old. Aswell as other hhd failed over the years). I have yet to se an ssd fail in front of my own eyes. And i have had 5 ssd over the time where one is sold and rest is still in my owner ship.
The ssd i have now is:
And old crucial m4 64 gb. Now retired os drive and only use for games. But even this ealy ssd with over 10000 hours power on and still at 85 % exspected life span left.
Rest of my ssd is all at 100 % even after one of them is 3 years old now.
Crucial mx300 275 gb
Samsung evo 850 250 gb
Samsung 950 256 gb m.2 nvme ssd. My current os drive.
Whats more impressive me is that these ssd has been throw hell and back, with hell i mean alot os ssd benchmark.that shut where down an ssd faster.
Ssd is truly in my opinion way more stable than those slow ugly harddrives :p
Harddrive is compare to ssd suicide loving peace of crap :kookoo:.
