# Benefits

> How DNA storage transforms density, durability, energy, speed, and verifiability  the core advantages of building on a molecular substrate.

## Extreme Density & Durability

One gram of DNA can store on the order of **215 petabytes** of information. Entire archives that today require climate-controlled data centers can be reduced to small vials. Preservation timelines extend from decades to centuries without active maintenance or refresh cycles.

<Note>
  Ancient DNA samples more than two million years old have been successfully
  sequenced demonstrating that the molecule remains readable far beyond the
  limits of any electronic medium.

## Core Benefits

  <Card title="Energy Savings" icon="leaf">
    Cold archives consume enormous energy keeping disks spinning and tapes
    refreshed. DNA at rest consumes nothing. Energy is only spent during write,
    query, or read operations transformative reductions in lifetime cost and
    carbon footprint at petabyte and exabyte scale.
  </Card>

  <Card title="Faster Access to Insights" icon="bolt">
    Biochemical selection and quotienting reduce the sequencing burden by two to
    three orders of magnitude. Queries that would take months of linear reads
    can be resolved in hours with a fraction of sequencing making large archives
    practical to use.
  </Card>

  <Card title="Verifiability" icon="shield-check">
    Every dataset written into DNA can be cryptographically anchored on-chain,
    binding molecular archives to digital proofs. Results are independently
    verifiable across time, institutions, and jurisdictions.
  </Card>

  <Card title="Scalability" icon="arrows-up-down-left-right">
    A library of a few hundred prefabricated components assembles into trillions
    of unique identifiers. As synthesis and sequencing throughput improve,
    capacity expands from petabytes toward exabytes without changing the
    underlying chemistry.
