Backblaze has set benchmarks for hard drive manufacturers yet again. The recent stats will allow companies to scale the performance of their products against the products of adversaries.
The brand of Backblaze has been attributed to evaluation of hard drives in recent times. Since the release of their annual hard drive failure rates in 2013, the company has tested the performance of a plethora of hard drive models. They achieve this feat by extracting stats from drives used in their data services. Last month, they utilized the chance to release the results for 2017. The company taxed the hard drives of all the major HDD makers to maintain diversity in their statistics.
The management back up their cloud storage support for customers using consumer hard drives. Such constitution allows them to analyze failure rates for different consumer hard drives at the end of each annual term.
In the year 2017, their usage boasted a whopping amount of 93,240 spinning hard drives. This rattling amount constructed of 1,935 boot drives and 91,305 data drives respectively. The company removes any drive that is not available for production in the annual result. Backblaze also insists on having at least 45 drives of each model to qualify it’s result for the report.
BackBlaze Annual Hard Drive Failure Statistics
It is apparent from the given results table that the performance of hard drives has improved year-on-year since 2015. The number of devices also grew exponentially, doubling its previous count in the last three years. The wide range of devices ensured that the results were all-inclusive. During the first among the trio of years, Backblaze had 45,566 drives which rounded up a failure rate of 2.35%. In 2016, their count rose up by 34,737 units, the highest among all three years. The average failure rate also dropped down to 2.00%. The following year, Backblaze accumulated results for 91,243 specimens, with the failure rate slumping as low as 1.83% across the collection.
On a closer observation, one can see that Seagate and Western Digital’s 6 TB hard drive models have put up a good fight. They did not only achieve significantly lower failure rates but were also consistent with the numbers of HDDs in operation each year.Western Digital’s 3TB hard drive’s performance had improved drastically from 7.81% in 2015 to 1.09% in 2017. But their numbers dwindled from 1,046 devices to a mere 180 drives in BackBlazes habitat.
A couple of hard drive models seemed to have smothered the alarms for failure by scoring 0.00% failure rates. But unfortunately, such achievements hold little value as only 45 units of those models were scrutinized.
Though, the result report offers an interesting insight and can be helpful for establishing basic knowledge. Still, for making a balanced comparison, it is mandatory that every model is strained under the same number of units.
