According to a report, there will be storage challenges concerning genomic data and the problem will be bigger than what has been told by YouTube and Twitter. A team of scientists said that it is expected that between 100 million and 2 billion human genomes will be sequenced by 2025 and two to 40 exabytes of data storage will be needed for that.

According to Michael Schatz, a professor at Cold Spring Harbor Laboratory in New York and co-author of the study, the data challenge is among the most important issues related to biology. According to Schatz, "Scientists are really shocked at how far genomics has come. Big data scientists in astronomy and particle physics thought genomics had a trivial amount of data. But we're catching up and probably going to surpass them".

It has been estimated by YouTube that by 2025, there will be annual storage requirement of one to two exabytes of video. It was anticipated by Twitter that it could be one to 17 petabytes per year.

It goes beyond the one exabyte per year that was estimated for the largest radio astronomy project of the world.

With declining costs of sequencing, genomes will be analyzed to a greater extent. It’s not that only human genomes that are sequenced could reach the count of millions. Genomic data is enormous for the reason that the number of data, which is stored for a single genome, is much larger than the genome’s size. It contributes to errors in sequencing in addition to preliminary analysis.
