We’re running out of space all the time and we’ll definitely want bigger drives as opposed to smaller drives. As one of our go-to hard drives in the lab, we hope that they don’t slip any further in the higher density ranges. Of that number, there were 1,980 boot drives and 108,660 data drives. Western Digital, however, falls to second place behind Hitachi this time, and unlike Seagate, they take a hit in the higher density platters starting at 3TB, over the results reported earlier this year. As of June 30, 2019, Backblaze had 110,640 spinning hard drives in our ever-expanding cloud storage ecosystem. The work seems to be paying off for them in those bigger drives. Perhaps the change talked about in our interview with them at CES 2012, when the company announced that they would be moving into a denser platter process. Interestingly, their 4TB drives are by far the most reliable, leading us to believe that a manufacturing process change may have taken place. Unfortunately, Seagate comes out on the bottom again, with the highest failure rates facing units that use their 1.5TB and 3TB technologies. Not only that, but the cumulative AFR of SSDs (from 2018 to 2021) is around 1.07, which is actually less than the 1.40 cumulative AFR of HDDs (from 2013 to 2021). Hitachi can definitely stand proud today as the drives that you will want to buy to backup and protect your data. Nearly all of the SSDs tested by Backblaze have an AFR of less than 1, with some models falling below the 0.6 AFR that Backblaze looks for in its most reliable drives. The chart shows an impressive lead over Western Digital and Seagate, which is great news for the company that was once synonymous with failed hard drives, and even earned the moniker of “Deathstar”, for their “Deskstar” product lines. Although smaller 2TB units seem to be moving up in failure rates, but only slightly. The big winner this time around was Hitachi, with the least amount of failures over 2, 3 and 4TB drives, versus other competitors. Here’s the latest chart with the numbers… Fast forward to September 2014, and a new report has emerged from Backblaze, once again pitting the power trio of hard drive makers in a battle royale in their data centers.
