“Data storage requirements for all four domains are projected to be enormous. Today, the largest astronomy data center devotes ~100 petabytes to storage, and the completion of the Square Kilometre Array (SKA) project is expected to lead to a storage demand of 1 exabyte per year. YouTube currently requires from 100 petabytes to 1 exabyte for storage and may be projected to require between 1 and 2 exabytes additional storage per year by 2025. Twitter’s storage needs today are estimated at 0.5 petabytes per year, which may increase to 1.5 petabytes in the next ten years. (Our estimates here ignore the “replication factor” that multiplies storage needs by ~4, for redundancy.) For genomics, we have determined more than 100 petabytes of storage are currently used by only 20 of the largest institutions ().”
