AI 中文摘要
脱氧核糖核酸（DNA）可稳定存在数千年而不降解，信息存储密度比现有技术高几个数量级，且因能耗低而环保。尽管这些优势使其成为档案数据存储的有前景候选方案，但DNA存储系统受限于高成本，尤其是DNA合成相关成本。本文提出一种综合成本模型，用于计算使用各类存储系统归档数据的成本。利用该模型，我们对DNA存储与领先的磁带及基于云的档案存储服务开展成本分析。此外，该模型可通过各类参数定制，以反映未来成本下降及其他与成本相关的趋势。我们的结果表明，在当前成本轨迹下，DNA存储成本必须下降8至9个数量级，才能与当今的数据档案技术在经济上具有竞争力。此外，我们探讨了未来数十年的多个“假设”场景，量化了缩小与磁带及云档案竞争力差距所需的成本下降速率。我们的研究结果强调，迫切需要加快DNA合成技术的创新与投资，以降低其成本，使DNA存储转变为实用的档案解决方案。
英文摘要
Deoxyribonucleic acid (DNA) remains stable for millennia without degradation, can store information at densities orders of magnitude higher than current technologies, and is environmentally friendly due to its low energy requirement. While these advantages make it a promising candidate for storing archival data, DNA storage systems are constrained by high costs, particularly those associated with DNA synthesis. In this paper, we present a comprehensive cost model for calculating the cost of archiving data using various storage systems. Leveraging our model, we conduct a cost analysis of DNA storage versus leading magnetic tape and cloud-based archival storage services. Furthermore, this model can be customised with various parameters to reflect future cost declines and other cost-relevant trends. Our results indicate that, under current cost trajectories, DNA storage costs must fall by eight to nine orders of magnitude to become economically competitive with today's data archival technologies. Moreover, we explore multiple "what-if" scenarios over the coming decades, quantifying the rate of cost decline required to close the competitiveness gap relative to tape and cloud archives. Our findings underscore the critical need for accelerated innovation and investment in DNA synthesis technologies to reduce their cost and transform DNA storage into a practical archival solution.
