Backblaze has figured out the biggest predictors of hard drive failure

Cloud storage provider Backblaze continues to share the wealth of information (not to mention hardware designs) it’s learning as it operates its 40,000-hard-drive, 100-petabyte storage service. On Wednesday, it shared its analysis of the 70-plus SMART data attributes that all hard drives report about their performance. Of those, Backblaze’s Brian Beach explained in a blog post, the company use five to predict failures, and the strongest might be related to uncorrectable read errors. “[O]nce SMART 187 goes above 0, we schedule the drive for replacement,” he wrote.

Backblaze’s 500-petabyte data center is more proof of the digital data explosion

Cloud backup provider Backblaze has moved into a new data center in Sacramento┬ácapable of storing 500 petabytes, or half an exabyte, of data. It’s not full yet (the company was storing 75 petabytes as of November), but the pace is picking up and it probably will be sooner than some might expect. The crazy part is that Backblaze isn’t even that big a company or that widely used a service. Facebook alone is building enough capacity to house 3 exabytes of data in each of its 3 cold storage facilities. Sometimes, I can’t help but think that we’re just digitally hoarding.
