SUMMARY

The discussion focuses on the comparison between S-layer protein-based data storage and traditional hard disks. S-layer proteins, with a diameter of 3nm, can position one magnetic particle per protein, potentially allowing for extremely dense data storage. Current hard disk technology achieves data densities of approximately 100 to 200 Gbit/in², which translates to a significantly lower density than what could be achieved with S-layer proteins. The calculations and comparisons highlight the advantages of protein-based storage in terms of miniaturization and data density.

PREREQUISITES
  • Understanding of S-layer protein structures and their properties.
  • Knowledge of data storage metrics, specifically Gbit/in².
  • Familiarity with basic calculations involving volume and density.
  • Awareness of current hard disk technology and its limitations.
NEXT STEPS
  • Research the molecular structure and applications of S-layer proteins in data storage.
  • Explore advanced data density calculations for various storage technologies.
  • Investigate the latest developments in hard disk technology and their performance metrics.
  • Learn about alternative data storage methods, including DNA data storage and their comparisons to traditional methods.
USEFUL FOR

Researchers in data storage technology, materials scientists, and engineers interested in innovative storage solutions and their potential advantages over conventional hard disks.

An S-layer protein is 3nm is diameter. Calculate number of proteins per mm3 of membrane. If the
protein is used to pattern a surface used for data storage - each protein molecule can position one
magnetic particle (1bit) compare this type of storage with current hard disks.

Just one question before I start calculating: Is it correct with "proteins per mm3 of membrane", or is it supposed to be "per mm2 of membrane", you think?

How thick is the membrane? If the spherical (?) proteins are packed in the membrane edge-to-edge, you are looking at dots of 3 nm diameter.

Current disk technology can store data at about 100 to 200 Gbit/in^2. Convert 200 Gbits/in^2 to bits/nm
