The overall result was that "As long as you run drives well within their allowed range of operating temperatures, keeping them cooler doesn't matter. Beach notes that the average temperatures for drives used in the Storage Pods run from 21.92☌ (71.45☏) for the "green" Seagate Barracuda LP drives to a relatively steamy 30.54☌ (86.97☏) for Seagate's Barracuda XT drives.ĭigging even further, Backblaze was able to show that only one drive model - the Seagate ST31500541AS 1.5 TB drive - shows an increase in failure rate as temperatures rise. It was when the company started looking at individual drive models that a correlation appeared. Their Backblaze Storage Pods use big fans so that the drives are usually quite cool, but the study showed absolutely no correlation between temperature and failure rates for the entire population of varied drives from a number of manufacturers. The bottom line? Contrary to the long-standing belief that hot drives fail sooner, their statistics show that only hot-running drives from one manufacturer seem to have a higher than usual failure rate.īrian Beach of Backblaze took a look at the data, which comprises results from more than 34,000 drives. Today's stats are rather interesting, taking a look at how drive temperatures affect failure rates. 194,749 drives were in use by the corporation as of. To learn more about how we can help you mitigate your risk click on the button below.The storage wizards at Backblaze have been analyzing the statistics on drive failures in their huge storage facilities, then posting the results on their blog. Backblaze is back with an update on its hard disk and SSD failure rates for the third quarter of 2021. It is imperative these failed drives are properly audited, securely contained, and destroyed onsite to help maintain compliance and offer piece of mind. 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. The chart isnt zero-based, so it might look like theres a decent amount of fluctuation at first glance, but in reality the drives ranged from an average of 34. 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. 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.
