![]() ![]() There's a new disk firmware out to hopefully fix this but it's the first time that I've seen a disk complain about being at such a warm, yet cold, temperature. Turns out that these don't like being below about 18 degrees C, they switch into a 'read after write' mode that affects their performance. We have a lot of HP EVA FC-SANs and some of them have their 1TB 'FATA' disks in them. Now obviously this isn't going to take into account of working in an Egyptian summer or an Antarctic winter but the point I'm making is that they don't actually NEED to be too cold, if you're comfortable with the temperature then your disk is too.Ī few have said that they shouldn't get too hot, and that's very true but I was really surprised recently when I discovered that disks can actually be too cold. out in the open in a regular office or home environment. The failure rate of the ST31500541AS does go up at higher temperatures This contrasts with most other drives we have, which don’t show that trend.Īlthough every drive will list its minimum and maximum temperature I believe that most if not all drive manufacturers design their drives to work at an 'ambient' temperature - i.e. The correlations of 0.17 and 0.11 are weak, but they are statistically significant. While the data ranges from 14 to 41 months depending on the drive model, this is the one cohort where we have comparable data on drives from all three of the major manufacturers: Seagate, Toshiba, and WDC. one drive does show some correlation between temperature and failure rates. We will finish up our look at hard drive life expectancy curves with three models from our collection of 14TB drives. ![]() ![]() And almost all of the drives are in the nice comfortable range from 15° to 30°. all of drives are well within the 0° (or 5°) to 60° that the manufacturers specify for the drives. Google found that temperature was not a good predictor of failure, while Microsoft and the University of Virginia found that there was a significant correlation.Īfter looking at data on over 34,000 drives, I found that overall there is no correlation between temperature and failure rate. Google and Microsoft have both done studies on disk drive temperature in their data centers. The drive should never exceed temperature ranges. With our newer model drives the maximum temperature is now at 60 degrees Celsius. The operating temperature range for most Seagate hard drives is 5 to 50 degrees Celsius. Some additional data points not mentioned in other answers: Note that Sean's answer correlates to the max value listed on Speedfan's hard disk temperature page, and that the results from that tool are aggregated observations only etc etc. The final stats show my drive ain't looking so good these days :) NOTE : your hard disk has 23 reallocated sectors. Essentially it will give you a reading of your drive's SMART status contextualised with real data from other users' disks, providing some interesting aggregated results. For our evaluation, we remove from consideration 231 drives which were used for testing purposes and those drive models for which we did not have at least 60 drives. Backblaze says this is due to the aging of the entire drive fleet, and as a result. Therefore, this report only includes 108,461 hard drives.Alfredo Milani Comparetti's awesome Speedfan can "access status info from EIDE/SATA/SCSI drives showing.internal data that can be used to diagnose current and future hard disk failures". At the end of 2020, Backblaze was monitoring 162,530 hard drives used to store data. The Q3 2022 AFR for all drives was 1.64, compared to Q2 2022's 1.46 AFR overall, and 1.10 AFR from a year ago. However, 199 drives (108,660 minus 108,461) were not included in the list above because they were used as testing drives or Backblaze did not have at least 60 of a given drive model. Of that number, there were 1,980 boot drives and 108,660 data drives. The table of lifetime failure rates below is over the period beginning in April 2013 and ending June 30, 2019.Īs of June 30, 2019, Backblaze had 110,640 spinning hard drives in its ever-expanding cloud storage ecosystem. It also released the lifetime failure rates for the hard drive models that are in service as of June 30, 2019. The percentage failure rates were revealed in a Backblaze blog and presented in a table: On This Page :Ĭloud storage service supplier Backblaze revealed the Q2 2019 failure rates for its installed hard drives. In addition, with MiniTool Partition Wizard, you can back up data and recover data to avoid data loss. Read this post to know the detailed information. Do you know the specific hard drive failure rates? Recently, Backblaze revealed its Q2 2019 and the lifetime hard drive failure rates. ![]()
