Backblaze: Q2 hard disk reliability statistics in 2019 Report backblaze: Q3 mechanical hard disk quality report in 2020 Seagate 4tb failure rate is the highest backblaze: Q1 global hard disk reliability report in 2020 backblaze: Q1 mechanical hard disk failure rate report in 2018 backblaze: Q1 hard disk reliability report in 2016 hgst failure rate is only 2% Backblaze: 5-year failure rate report of mechanical hard disk. Kroll Ontrack: 72% of the data loss is caused by hardware failure. Backblaze: the research shows that the profit margin provided by hard disk mining Chia is very low. Backblaze: the higher the working temperature, the more likely the hard disk is to fail. More reading of zikuai Technology: backblaze: Q4 and annual hard disk failure rate report in 2016 backblaze: Q2 global hard disk reliability report in 2017 hgst is the most reliable backblaze: Seagate’s hard disk failure rate in 2021 is higher than that of other manufacturers backblaze: Q2 hard disk failure rate report in 2020 hgst is still the most reliable backblaze: Q3 global mechanical hard disk failure rate report in 2017 has the highest failure rate of 4tb backb Laze: the data shows that the overall failure rate of hgst hard disk is the lowest, and the average service time is up to 5 years. The average service time ranged from 1 month to 6 years, and the final value was 1.43%.īackblaze also said that according to the monitoring of HDD and SSD data, although the SSD failure rate is lower, over time, both SSD and HDD will be affected by performance aging, and AFR will gradually improve. Among them, the average life of Seagate 6tb hard disk (st6000dx000) and Toshiba 4tb hard disk (md04aba400v) has exceeded 75 months, which is even better.īackblaze also counted the AFR (annual failure rate) of all backblaze hard disk models involved in sampling from Apto September 30, 2021, covering hard disks from 4tb to 16TB. In addition, Seagate 6tb hard disk (st6000dx000), Toshiba 4tb hard disk (md04aba400v), Toshiba 14tb hard disk (mg07aca14tey) and WDC 16TB hard disk (wuh721816ale6l0) recorded only one hard disk failure in Q3. This product is used for backblaze on Dell storage server in Amsterdam data center. #BACKBLAZE HARD DRIVE RELIABILITY 2020 FREE#However, it remains to be seen how the faster storage medium fares in the future, especially when it comes to endurance (TBW) and long-term reliability.Īs for lifetime figures of data HDDs active until Q2 2021, Backblaze published the following table, alongside the best performing models with the lowest lifetime AFR percentage arranged in decreasing order of drive size/capacity.Among them, Hitachi hgst 12tb is the only fault free hard disk product (Hitachi has been acquired by western data). With HDDs failing as they age and slowly adding to their lifetime AFR percentage, Backblaze recorded a slight dip for SSD failures this year, coming in at 0.79 percent over last year's 0.84 percent AFR. Now, the latter's lifetime AFR value comes in at just under twice that of SSDs. This evaluation drastically reduced the AFR difference between the two storage mediums, which in Q1 2021 stood at 0.65 percent for SSDs and 6.04 percent for HDDs. Meanwhile, for a more accurate comparison of boot drives that are made up of older HDDs and relatively newer SSDs, Backblaze first looked at the active drives' figures from Q4 2020 and then a lifetime snapshot from Q4 2015 for boot HDDs, which is when their attributes (drive count, average age) were the closest to the SSDs. The AFR for these data drives rose to 1.01 percent, which Backblaze notes is a jump from 0.85 percent over the previous quarter and has also ended the downward AFR trend observed over the past year. The three models with only one unit going bust this quarter include Toshiba's 4TB and 16TB drives, the latter of which recorded its first failure, alongside one HGST 8TB unit. The other two being HGST's 12TB and WD's 16TB drives. Interestingly, the company's 6TB HDD was among the three HDD models that recorded zero failures in Backblaze's Q2 2021 reliability report. In terms of quarterly failures, Seagate's 4TB HDD led the pack with 91 units out of a total of 439 failing drives. Backblaze also drew a comparison between its SSD and HDD boot drives by looking into past data for a more accurate insight into their failure rates. The company noted a slight increase in quarterly AFR across its data drives, which were expectedly led by a couple of Seagate and Toshiba models that have one of the highest drive counts and average age across all monitored HDDs. Bottom line: Backblaze has published the latest reliability figures for its data drives (HDDs) and boot drives (SSDs and HDDs) for Q2 2021.
