I dont know about you, but my system is online 24/7 here.. but I do not run a data center.
I start noticing how Seagate drives were failing in my systems back in 1985. I went to Maxtor, and quit losing drives. Then in the early 1990s, I started a business, and we were creating custom software for clients, and then installing custom built computers and networks, and training everyone there on how to use the systems. About a year after starting the business, two new clients specifically requested Seagate drives, which up to that point we had not been selling. To get the contracts, I agreed to use Seagate drives for them. A little over a year later, I was looking at the hard drive failure rates, and the Seagates were dying at 2.5 times the other brands. I talked to the management of the two companies, and they agreed to allow us to replace dying drives with other brands. Nearly all of these computers were operating about 12 hours a day. There were hundreds of systems in place, with a dozen or so server boxes. The servers were online 24/7.
And then decades later, BackBlaze shows up. And the exact same problems are happening in their data center that I saw back in the 1990s. And last year, the updated chart, which is the one I posted here, showed most of the failure rates increasing over the course of the year.
So that makes me think this problem has been going on for over 30 years, in various business environments, and Seagate has never resolved the problem.
