Advancements in Hard Drive Technology: Moore’s Law and the Promise of Project Millipede

Explore how Moore's Law continues to influence hard drive technology into the 21st century. As IBM's Project Millipede promises to revolutionize data storage with smaller read/write tips and higher aerial densities, we examine the challenges of maximizing disk capacity and the future potential for hard drives. Current maximum capacities are approaching limits, but innovations like 100 Gb/in² can extend storage possibilities. With aspirations for densities reaching 500-1000 Gb/in², the future of compact data storage looks promising, especially for laptops and portable devices.

  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
