Backblaze sees above average failure rates with Seagate 12 TB drives

Interesting, Seagates has had a few other questionable models in the Backblaze charts in the past. HGST and Toshiba have both done well much of the time.
Ugh, their numbers are a prime example of misuse of data without giving a confidence interval/level.
Is 5 failures out of 99 statistically significant when compared to 386 out of 14,416? To what extent is their conclusion that Seagate 12 TB drives worse statistically supported?
This is basically what they tell is not to do in high school statistics.

Backblaze hard disk stats for 2019 (with the actual data) are not yet ready. The differences between the manufacturers (HGST, WD, Seagate, Toshiba) which were quite pronounced a few years ago have largely disappeared in their experience. So this finding was exceptional, prompting the preliminary blog post.
