Backblaze, a company that provides cloud-based backup, has compared which hard drives from its servers failed during 2015 and claims that a particular brand is problematic much more than the others.
The results of this report are interesting, mainly because Backblaze uses off-the-shelf hard drives for its servers, rather than business-grade data storage equipment.
The company claims that during 2015, it used 56.224 HDDs placed in 1.249 storage pods, already having 39.690 hard drives at the beginning of the year.
Its hard drives range from 1TB to 8TB, and the company reports that it sources them only from four hard drive manufacturers: HGST (formerly Hitachi Global Storage Technologies), Seagate, Toshiba, and Western Digital.
Backblaze notes in its report that hard drives tend to fail in different ways depending on brand, model, capacity, and data fill level. However, the company's Western Digital products failed almost twice as often as the company holding second place.
According to 2015 data, Backblaze reports that Western Digital hard drives had an annual failure rate of almost 7%, followed by Seagate with almost 4%, third Toshiba with almost 3.5%, and finally HGST with a failure rate just over 1%.
It is worth noting that the company's servers primarily use 4GB hard drive units. In this category of hard drives, the leader in failures is Toshiba, followed closely by Seagate, while Western Digital and HGST had better results. better.
