Western Digital Drives Compared to Seagate & Toshiba, More Likely to Fail
Monday, 22 February 2016 00:00

Backblaze, a company that provides cloud-based backup solutions, has studied how its data center's hard drives failed during the past year and claims that one particular brand fails more than the others. The result of this report may interest you more than any other, mainly because Backblaze uses off-the-shelf hard drives for its data centers, not business-grade data storage equipment.

The company claims that during 2015, it used 56,224 HDDs organized in 1,249 storage pods, growing from 39,690 HDDs which it had at the start of year. Hard drives varied from 1TB to 8TB storage, and the company says it only used four hard drive manufacturers, which were HGST (formerly Hitachi Global Storage Technologies), Seagate, Toshiba and Western Digital. While Backblaze observed in its report that hard drives tend to fail differently depending on their make, model, and capacity, aggregating the data, one company's products failed almost twice as often as the second-placed competitor.

“Western Digital hard drives had the biggest failure rate” Below our images that were posted on the blog of BackBlaze.

Backblaze says that Western Digital hard drives had an annual failure rate of nearly 7%, followed by Seagate with almost 4%, Toshiba with nearly 3.5%, and HGST with a failure rate of just over 1%. It's worth noting that the company's data center used 4TB hard drives in most of its storage pods.

This is particuliraly bad news for Western Digital. Backblaze are very well known and have been eatured in many articles globally for the solid busines moel they are provided. When one of your partners comes out and says that you not performing especially when being compared to your rivals makes it all the worse to digest. Western Digital will need to ensure that the new HDD technoology they release going forward will suffice in the eyes of its major partners. Only time will tell.
