- By 2025, between 100 million and 2 billion human genomes are expected to be sequenced, requiring as much as two to 40 exabytes (one exabyte equals one quintillion bytes) of data storage, according to a team of scientists.
- This outstrips YouTube's projected annual storage needs of one to two exabytes of video by 2025 and Twitter's projected one to 17 petabytes per year (one petabyte is 1,000 terabytes or 1,000,000 gigabytes). The amount of data that must be stored for a single genome are 30 times larger than the size of the genome itself, to make up for errors incurred during sequencing and preliminary analysis", Nature claims.
- Storage however, is not the only challenge as computing requirements for acquiring, distributing and analysing genomics data can be demanding both in terms of data volume and the speed of analysis required.
