blog-drive-study

At Backblaze we now have 34,881 drives and store over 100 petabytes of data. We continually track how our disk drives are doing, which ones are reliable, and which ones need to be replaced. I did a blog post back in January, called “What Hard Drive Should I Buy?” It covered the reliability of each….

How much does operating temperature affect the failure rates of disk drives? Not much. The unlimited online backup service provided by Backblaze requires a lot of storage.

My last two blog posts were about expected drive lifetimes and drive reliability. These posts were an outgrowth of the careful work that we’ve done at Backblaze to find the most cost-effective disk drives. Running a truly unlimited online backup service for only $5 per month means our cloud storage needs to be very efficient….

Over 100,000 people read that blog post and one of the most common questions asked was: “Ok, so the consumer drives don’t fail that often. But aren’t enterprise drives so….
