Cloud backup provider is fast becoming one of my favorite companies in IT, if only because it shares so much information about its operations. On Tuesday, the company — famous for its open source storage-pod designs and infamous for getting blacklisted from stores including Best Buy and Costco during the 2010 hard drive shortage — released a new set of data regarding the lifespan of the hard drives on which its service runs.
Backblaze Distinguished Engineer Brian Beach provides a lot of detail in a blog post about the study, but here are the highlights:
- The company is storing 75 petabytes of customer data on more than 25,000 consumer-grade hard drives.
- It has been in business for 5 years and 74 percent of the hard drives it has ever deployed are still running.
- Annual failure rate for drives is 5.1 percent for the first 18 months, 1.4 percent for the next 18 months, and 11.8 percent during years three and four.
- By Backblaze’s estimates, more than half of its drives could still be running after 6 years — a finding most studies on hard drive lifespans to date would not have predicted.
The direct implications of the study beyond the borders of Backblaze’s business are unclear — its cloud backup service is certainly different than running a large web operation like Google, or even an application-serving storage service like Amazon S3 — but the numbers are interesting nonetheless. Taken as a whole, the efforts of companies like Backblaze and organizations like the Open Compute Project suggest a future where intrepid CIOs can legitimately question prior assumptions about how much hardware should cost, what it should look like and how long it should last.
