Exceeding the Limit of Earth-Based Storage

From a PDF presentation on Sun’s ZFS (emphasis mine):

ZFS Scalability

  • Immense capacity (128-bit)
    • Moore's Law: need 65th bit in 10-15 years
    • Zettabyte = 70-bit (a billion TB)
    • ZFS capacity: 256 quadrillion ZB
    • Exceeds quantum limit of Earth-based storage
