Symposium Objectives

• Review Technical Attributes of HDD and Flash Technologies

• Determine Present and Future Applications for Each

• What HDD FF Are Required To Meet Applications

• What Flash Products Are Required to Meet Applications

• Areas Where Each Will Compete

• Areas Where Each Will Coexist

• Areas Where Each Could Dominate

Ed Grochowski

Scope of Study

1. Consumer Based Applications• Digital Still Cameras• Video Cameras• Mobile phones• MP3 Players• GPS• Games

2. Small FF HDD, 2.5 inch, 1.8 inch, 1.0 inch, 0.85 inch

3. Flash Capacities

4. Unit Prices and Projections

Ed Grochowski

Why This Symposium?

1. Explosion of Storage For Consumer Based Applications

2. SFF HDD Have Made Inroads in Traditional Flash Territory

3. Demand For Higher Storage Capacities May Open New Opportunities For SFF HDD

4. Both Flash And SFF HDD’S Are Evolving

5. In Certain Applications Both Technologies Will Coexist

HH Units TAM by Form Factor

• 1.8” • Significant upside but limited growth• High-end HH devices – photo MP3,

Portable Media Player• 1.0” 2hd

• Estimate 500% growth rate from 2004 to 2005

• MP3 player explosion • Market is still supply limited

• Mobile Phone FF• 2.5G technology support Messaging

Service(i.e. SMS)• Started to adopt 3G technology which

enables up to 2 Mbps transfer rate• Estimate 60M units smart phone and

390M units of camera phone in 2005
