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.
