Molecular Storage Rod DNAStore Prototype Unveiled: 1 Gram of DNA Stores 215 PB of Data for a Millennium
Microsoft Research and the University of Washington have jointly unveiled the DNAStore molecular storage rod prototype, encoding data as DNA base sequences to achieve 215 PB per gram of storage density with a data preservation lifespan exceeding 1,000 years
Molecular Storage Rod DNAStore Prototype Unveiled: 1 Gram of DNA Stores 215 PB of Data for a Millennium
Microsoft Research and the University of Washington have jointly unveiled the DNAStore molecular storage rod prototype. The device encodes digital data as DNA base sequences (A, T, G, C), encapsulated in miniature quartz glass tubes, achieving a storage density of 215 petabytes per gram.
DNAStore's write speed is 400 MB per second, and its read speed is 200 MB per second, with random access enabled through nanopore sequencing technology. While these speeds are far below those of traditional SSDs, the technology has an overwhelming advantage in long-term archival scenarios — data preservation exceeds 1,000 years, far surpassing magnetic tape's 30 years and optical discs' 100 years.
Karin Strauss, Principal Researcher at Microsoft Research, said: "Global data volumes double every two years, but the capacity growth of physical storage media falls far short. DNA storage is the only known technology capable of keeping pace with the data growth curve."
The first commercial products are expected to arrive by 2032, primarily targeting government archives, genomic databases, and cold data storage needs of cloud service providers.
