![]() Ok, so what the heck was going on with that final drive? That’s a virtually unprecedented failure rate that has officially blown our minds! If you have one, this article is definitely going to help you at some point! The only question is when. Seagate ST3000DM001, 3TB – 26% failure rate. ![]() And the top 3 drives to be avoided in 2017 are: While BackBlaze really takes a positive angle on their whole study and don’t specifically note failing models in their summary, you can actually read a chart that shows who the losers are. What is quite interesting about the 8TB size is that the site shows that the drives failed far less as the year went on! Which is odd, but does factor in. But, facts are facts and these guys do run a number of hard drives in their servers, so we’re not talking about small sample sizes. So 8TB appears to actually be somewhat of a sweet spot for the company, which is a little surprising considering that these are monster sized drives. The 8 TB Seagate (ST8000NM0055) drives, which were deployed in November 2016, also recorded no failures. Both the 4 TB Toshiba and the 8 TB HGST models went the entire year without a drive failure. In 2016, three drives models ended the year with zero failures, albeit with a small number of drives. And in this case, BackBlaze has three fine examples of failure free hardware: Naturally, everyone is going to want to know what the winners are. That’s down from 2.47% in 2015 and well below the 6.39% failure rate for 2014. The overall hard drive failure rate for 2016 was 1.95%. Of course, that’s easy for me to say, since I am not the one swapping out drives. That’s 3.36 drive failures per day or about 5 drives per workday, a very manageable workload. The total number of failed drives was 1,225 for the year. But their results for the year do show, hopefully, that manufacturers are getting better at building robust drives: A lot of their data is based around enterprise servers, which typically contain much more powerful drives. And certainly, not all of the models are going to be ones that you will typically use in your computers. Ok, so Backblaze has a freaking ton of hard drives. This leaves us with 71,939 production hard drives. For our evaluation we remove from consideration those drives which were used for testing purposes and those drive models for which we did not have at least 45 drives. Of that number, there were 1,553 boot drives and 72,100 data drives…Īt the end of Q4 2016 Backblaze was monitoring 72,100 data drives. At the end of 2016 we had 73,653 spinning hard drives. Their methodology is:īackblaze has recorded and saved daily hard drive statistics from the drives in our data centers since April 2013. Well, we think so, and apparently so does, as they actually have a hard drive failure rate study up on their website. But what about the idea of avoiding risk by finding out which manufacturers tend to sell the drives that fail the most? I mean, if you had some way of tracking which hard drive companies you should avoid and which ones you should buy from, wouldn’t it make the whole data safety concept a whole lot better? This is what backups are for, of course, and certainly doing that is going to ensure that there’s practically no way you have to require a data recovery company like Hard Drive Recovery Group or our services. It’s basically a fact that when it comes to hard drives, whether they are old platter and spindle style or brand new SSD style, you’re best to not trust them on their own.
