HGST is the reigning champion of hard drives when it comes to reliability, according to cloud backup provider Backblaze, which should know since it deploys tens of thousands of drives to run its unlimited backup service.
Backblaze posted an interesting blog that examines the failure rate of the hard drives it uses in its data centers. The company ran a similar test last year and found that its HGST drives were running the longest compared to other brands, but when it came to performance, it was hard to beat Seagate.
This year, the company examined 39,696 disk drives used to power Backblaze’s unlimited backup service and one again found out that Hitachi drives tend to fail less than the other drives. Backblaze also discovered that the Seagate 4 TB drives it maintains (apparently over 12 thousand devices) don’t have quite as low of a failure rate as the HGST drives, but their low price make them a good deal.
If you’re into learning more about how Backblaze performed the test, you’ll definitely want to read the whole post.
Here’s a look at the hard drive failure rate per manufacturer:
