As of December 31, 2019, Blackblaze was active 124,956 hard drives, hence the empirical details may be regarded as reliable. Of that number, 2,229 were disk drives and 122,658 disk drives, from which this figure is derived. It should be noted that as the years went on, the company added more hard drives, and when some years ago the larger discs had 4 TB, they now have units up to 14 doses of TB.
The most unreliable hard drive of 2019
As we have previously shown, 122,658 hard drive machines were used, discarding those that did not reach 5000 driving days (they did so to give more credibility to the data, avoiding new disks, according to Gauss's instrument, failing at the beginning of his life), staying inside 122,507 units counted.
As you can see, a total of 1.89% of the drives used failed somewhere, only the Toshiba 4TB did not have a broken drive. Can we say it is very reliable? Not necessarily, since it is also a model with very small units and, therefore, in mathematics its ratio is compact.
So the strongest drive of 2019 according to this figure is 12 TB HGST (There are two of these actually, with a failure rate of 0.4% and 0.56%), followed closely by the 4 TB model of the same product, and don't forget the 14 Toshiba's 14, with only 14 TB Toshiba, only the failure rate of 0.65%.
In contrast, unreliable hard drive machines have turned into 12 Seagate for TB with a failure rate of 3.32%, followed by 4 Seagate of 4 with 2%.
Comparing reliability over time
As you can see, during 2019 many hard drives have failed more than during 2018 and 2017, but it is also true that the number of units has grown by almost 32,000 in just two years. In any case, the statistics are there to show us whether by chance or unfortunately, the most reliable driver equipment usually comes from HGST followed by that of Toshiba, while Seagate's driving machines are often in the tail of trust.
Finally, here we can see the final statistics table showing the reliability of hard drives from 2013 to 2019.
Here we can see the statistics more clearly, but also the winners repeat: the 12 TB disk of HGST is the smallest failure, at a rate of only 0.40%, and the worst fails is Seagate 4 TB with 2.67% ( not that it's too high, it's all said).
