The 6TB from Seagate seems to have very good reliability in my opinion. Comparing Hard Drive Failure Rates Over Time When we compare Hard Drive stats for 2018 to previous years two things jump out. While these statistics cannot be used to reliably judge the quality of drives from any particular manufacturer they serve as a good reference for general trends in hard drive reliability. The least reliable drive is also from Seagate with the 14 TB ST14000NM0138 having an AFR of 4.66% in Q4 2021 down from 6.29% in Q3 2021. The most reliable drive operated by Backblaze remains the 6 TB Seagate ST6000DX000 with an AFR of just 0.11% while having an average age of 80.4 months. The larger capacity newer drives are primarily responsible for this figure with them accounting for 69% of total active drives but only 57% of drive failures. The latest report shows that the AFR for all drives in operation rose to 1.01% in 2021 up from 0.93% in 2020 but significantly below the 1.83% reported in 2019. The company operates drives of various capacities and ages from Seagate, Toshiba, HGST, and WDC monitoring each models annualized failure rate (AFR). ![]() To learn more about how we can help you mitigate your risk click on the button below.Backblaze, a cloud storage provider has recently released their latest annual report on the performance of their 202,759 hard disks in operation. It is imperative these failed drives are properly audited, securely contained, and destroyed onsite to help maintain compliance and offer piece of mind. Backblaze is back again with a new update on its hard drive and SSD failure rates for the 3rd quarter of 2021.As of September 30th, 2021, the company had 194,749 drives spread across four data. Having failed drives lying around is a recipe for disaster, or rather, a recipe for a data breach. With more light shed on just how high drive failure rates are, it is important that the above questions are considered. What happens to those drives when they fail? Do they sit on a desk? In a box or plastic tub? Are the individual drives accounted for as they are removed from their working environment? This also means currently there are hundreds of thousands of drives active in an environment that could have a failure rate as high as 25%. More importantly it means more data at rest, which greatly increases the chance of a data breach from data walking off. Backblaze is back again with a new update on its hard drive and SSD failure rates for the 3rd quarter of 2021. A failed drive can create server downtime and more work, which means less time for other tasks. What does this mean to everyone? What it means to data centers and data center managers is they need to be more careful what brand they buy, for a few obvious reasons. This is not always, and usually isn’t always the case. Now keep in mind, these drives are running in near optimal conditions, as this is a data storage company. They had a range of 3.8% to a whopping 25.4%. The surprising figures come from Seagate, of the 3 major brands tested Seagate was the worst. Western digital drives failed at a slightly higher rate of around 2.5% to 3.5%. These numbers are closer to what manufacturers will tell you, but they are among the few in this category. ![]() Hitachi came out on top with less than 2% overall failure rate, their actual numbers were 0.9% to 1.1%. To the left you can see how each of the three brands did. Backblaze measured the reliability of the drives based on their annual failure rate, which is the average number of failures while running a drive for one year. The most attention was given to the top 3 in the industry, Hitachi, Western Digital, and Seagate. Many drives performed as expected, some did better than expected, and others failed miserably. The study consisted of over 25,000 drives (27,134 to be exact) from the industries top manufacturers Hitachi, Seagate, Western Digital, Toshiba, and Samsung.īackblaze took all of the drives and put them into their environment and kept a close eye on them to see how they would perform. Online backup specialists Backblaze completed a study on the reliability of hard drive brands currently on the market, and the results were very interesting. ![]()
