Resumé:
The demand for data-driven decision-making coupled with need to retain data to meet regulatory compliance requirements has resulted in a rapid increase for data stored by enterprises. As data generation rate far outpaces the rate of improvement in storage density of media like HDD and tape, researchers have started investigating new architectures and media types that can store such “cold”, infrequently accessed data at very low cost. Synthetic DNA is one such storage media that has received some attention recently due to its high density and durability. DNA possesses three key properties that make it relevant for archival storage. First, it is an extremely dense three-dimensional storage medium that has the theoretical ability to store 455 Exabytes in 1 gram; in contrast, a 3.5” hard disk drive can store 10 Terabytes and weighs 600 grams today. Second, DNA can last several centuries even in harsh storage environments; hard disk drives and tape have life times of five and thirty years. Third, it is very easy, quick, and cheap to perform in-vitro replication of DNA; tape and hard disk drive have bandwidth limitations that result in hours or days for copying large Exabyte-sized archives. In project OligoArchive, we will investigate the use of Deoxyribo Nucleic Acid (DNA) --- a biological substrate – as a medium for storing digital information. Over the course of this project, we will develop the fundamental technologies needed to make long-term data archival using DNA cost effective and realizable in practice.
