Cloud backup provider Backblaze has moved into a new data center in Sacramento capable 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.
