![]() If you take part you will witness the Backblaze team dig deeper into quarterly, yearly, and lifetime hard drive stats – and more. If you find the above facts and figures particularly interesting Backblaze is presenting a webinar ‘ Backblaze Hard Drive Stats for 2017’ on Thursday 9 th February, 2018 at 10:00 Pacific time. This report will review the quarterly and lifetime failure rates for our. The boot drives consisted of 1,669 hard drives and 1,518 SSDs. In the past, Backblaze has gained notoriety for reporting on the annualized failure rates of the hundreds of thousands of hard drives it has spinning in its storage pods. Of that number, there were 3,187 boot drives and 172,256 data drives. Backblazes most recent study, the results of which were also published in a company blog post, delved into SMART alerts based on the 40,000 or so hard drives the company has in its data center. By the end of the year there were none but it had gained about the same number of 12TB HDDs and significantly “bulked up” on 8TB devices. As of March 31, 2021, Backblaze had 175,443 drives spread across four data centers on two continents. At the start of the year there were six or seven thousand 3TB HDDs in its servers. Last year Backblaze significantly skewed the HDD capacity mix it employs. One instance of the drive may say 'Unplugged' and appear selected for backup - Select the instance of the drive that is not listed as 'Unplugged' 5. Under 'Select Hard Drives to Backup' locate the drive. These drives are “amazing,” gushed the Backblaze blog. Open the Backblaze System Preferences/the Backblaze Control Panel. The cloud storage company is most impressed, however, by its HGST/Hitachi 4 TB models, which delivered sub 1 per cent failure rates for each of the three years. Weighing up this data Backblaze notes that 6TB Seagate and WDC models seem to be getting more reliable. Above you can see annualised failure rates by year for 2015, 20. On the other side of this volatility an 8TB HGST drive looks to offer enviable reliability, for example.īackblaze has put together a longer term chart which is good to see as most of us expect an HDD to last many years. For example the Seagate 4 TB drive, model ST4000DM005, has a annualized failure rate of 29.08 per cent, “but that is based on only 1,255 drive days and 1 (one) drive failure”. You will note that the AFR figures vary widely and Backblaze admits the figures can be volatile, “especially for models that have a small number of drives and/or a small number of drive days”. ![]() Since 2013 the company has been monitoring and reviewing reliability of the HDDs it uses and it has periodically, and generously, shared its findings for 2017 a couple of days ago via its official blog.Ībove you can see Backblaze’s Hard Drive Annualised Failure Rates (AFR) for the most recent quarter. ![]() The company ended the year with 93,240 HDDs in operation that’s 1,935 boot drives, and 91,305 data drives. At this point, you are better off deciding based on other factors: cost, speed required, electricity, form factor requirements, and so on.Cloud storage data centre company Backblaze has just published its review of 2017, with regard to hard drive reliability and related stats. Multiple Cloud Storage Manager: Migrate, move, sync, copy, backup and transfer cloud files with MultCloud, which supports Dropbox, Box, Google Drive, Mega. Once we controlled for age and drive days, the two drive types were similar and the difference was certainly not enough by itself to justify the extra cost of purchasing a SSD versus a HDD. Klein wrote: “Where does that leave us in choosing between buying a SSD or a HDD? Given what we know to date, using the failure rate as a factor in your decision is questionable. That might be a network problem, or it might be your cluster authority is offline, or some other issue. To make the comparison fair, it compared the SSD failure rates to the HDDs used for boot drive duty at a similar age in their life cycle and found similar failure rates. What the Backblaze problem that is occurring is that your particular 'cluster authority' cannot communicate with the global mapping server that maps your email address to your cluster. In short, the Ironkey Keypad 200 is like a mini Fort Knox for your. It monitors its disk drive reliability and does the same for its SSDs, so it can compare their failure rates. However, Backblazes blog points out that Backblaze doesnt have any 1TB, 1. Cloud backup and data storage provider BackBlaze is finding its SSDs fail at nearly the same rate as its disk drives at the equivalent stage in their life cycle.Ī Backblaze blog by Andy Klein, its oddly titled Principal Cloud Story Teller, outlines how Backblaze used to boot its systems off disk drives and then started using SSDs instead.
