    摘要:

    自人类进入信息时代以来,全球信息总量飞速增长,对数据存储行业带来极大挑战。目前的信息存储工具存在如信息密度低、使用年限短、环境污染等许多缺陷,而脱氧核糖核酸(DNA)作为天然的遗传信息载体,其信息密度高、稳定性高、保存时间长、维护成本低等特点,或可成为信息存储领域的一项优秀选择。尽管DNA存储目前面临着读写成本高、速度慢、错误率高等挑战,但其在许多领域也有着独特的优势,如“冷”数据存储、军事加密存储等。目前DNA存储的潜在发展方向主要包括在军事、空天等特殊场景下的应用,高容错的编解码方案,生物活体存储体系,脱离测序的信息读取方法,集成化的存储系统及统一行业标准等。希望在不久的将来,DNA存储可实现规模化的应用落地,开启数据存储新纪元。

    Abstract:

    Since the human civilization entered the information age, an exponential growth of digital information globally posed great challenges to data storage. Current data storage devices have many defects, such as limited data density, short lifespan, environment pollution and so on. Deoxyribonucleic acid (DNA), the natural carrier of genetic information, was proposed to be a reasonable alternative due to its high information density, robustness, long half-life and low maintenance cost. Although DNA storage currently faces the challenges of high reading and writhing costs, slow speed and high error rate, it has unique advantages in many fields, such as long-time archival storage, military data encryption and so on. The potential future directions of DNA storage mainly include applications under special scenarios such as space data center and military, encoding-decoding algorithms robust to base errors, in vivo DNA storage, information retrieval without sequencing, and integrated DNA storage system as well as a unified evaluation standard. We hope that in the future, DNA storage can achieve large-scale application, and open a new era of data storage.
