DNA Data Storage Platform HelixVault Goes Commercial: 1 PB Per Cartridge, Millennium-Long Durability

Global data volumes are growing at 25% annually, but traditional storage technology capacity improvements can't keep up. Hard drive capacity grows about 15% per year, flash about 20%. At this trajectory, the world will face a hard storage capacity bottleneck by 2035. DNA data storage is seen as the ultimate solution, but has long been confined to the laboratory due to read/write speed and cost limitations.

On July 1, 2028, US storage technology company Helix Bio announced the commercial launch of its DNA data storage platform HelixVault. The platform encodes digital information into synthetic DNA's four base sequences (A, T, G, C). A single storage cartridge contains approximately 50 grams of synthetic DNA with 1 PB (1,000 TB) capacity and a theoretical lifespan exceeding 1,000 years.

HelixVault's technical breakthroughs come in three areas. First, write speed: Helix Bio's "parallel synthesis engine" technology simultaneously writes data across millions of DNA strands, boosting write speed from a few KB/s at laboratory level to 200 MB/s. Second, read speed: an improved nanopore sequencing technology achieves 500 MB/s read speeds. Third, cost: storage cost is approximately $0.02 per GB, still above hard drives at $0.01 but competitive for cold data archiving scenarios.

Helix Bio CEO Dr. James Mitchell said: "DNA storage's advantage isn't just capacity—it's durability. Hard drives degrade in 5 years, tape in 10, but DNA can last over a millennium under proper conditions. For data that needs to last centuries—government archives, medical records, cultural heritage—DNA is the only truly reliable medium."

First customers include the US National Archives, Norway's Svalbard Global Seed Vault digitization project, and China's National Library.

DNA storage works by mapping binary data to four bases, then physically synthesizing the base sequences. Reading reverses the process through sequencing. The key challenge is error correction—DNA synthesis and sequencing introduce random errors, requiring robust error-correction coding. Helix Bio uses an improved Reed-Solomon code, keeping error rates below 10^-15.

But DNA storage isn't a perfect replacement. The biggest limitation is random access speed: while sequential reads are fast, locating and reading specific files from petabyte-scale DNA storage still takes minutes to hours, making it suitable only for cold data archiving.

Helix Bio offers managed services and full on-premise deployment starting at $500,000. China's Institute of Computing Technology announced on July 3 that it is developing a domestic DNA storage platform, expected to deliver a prototype by 2029.
