  1. A Smaller Future Maintaining Moore’s Law, as applied to hard drives, into the 21st century John Stephenson

  2. Moore’s Law • 1964 Gordon Moore • Doubling time • Not stopping

  3. Moore’s Law of Hard Drives • Has been extended to aerial density • Doubling time: 12 months • Current drives • Maximum capacity is 66GB per disk • 3 disks  200GB

  4. Coming to a close • IBM’s ‘Pixie Dust’ • Future disks: 133GB / disk • Increasingly difficult to fit more data onto the same disk • Far away from the dreams for many TB of storage

  5. IBM: Project Millipede • Works like a punch card • Smaller holes: 10nm • Thin polymer film • 1000s of read/write tips

  6. Details • How does it write? • 400°C tips • How does it read? • 300°C tips • Write/overwrite 100,000x • Lower energy demands

  7. Room for Expansion • Without ‘Pixie Dust’ 25 Gb/in2 has been realized • With it, 100 Gb/in2 is expected this year. • With Millipede, currently 200 Gb/in2 • Allows for smaller sizes • Especially important with laptops (40GB) • Future density • 500-1000 Gb/in2

  8. The Future is Small • Project Millipede is going to out compete magnetic media • It is going to keep Moore’s Law alive, well into the 21st century
