1 Examine Your Strategy, Weigh Your Options in Choosing Removable Storage Dave Holmstrom Associate Director of New Products Verbatim Corporation

2 Evaluating Storage Solutions What type of data is being stored? How much will you need to store? How quickly do you need to access the data? Will people need to share and distribute data with others? How reliable are the various storage media? Finally, how much are you willing to spend?

4 Growing Storage Requirements (Petabytes Shipped) * Forcasts Source: IDC * 99* 2000* A Petabyte = 1 quadrillion bytes of data

5 Storage Equivalents Text Storage 1TB (terabyte) = 500 million text pages 1PB (petabyte) = 500 billion pages 1EB (exabyte) = 500 trillion pages 1GB (gigabyte) = 500,000 text pages 1MB (megabyte) = 500 text pages Still Video Storage.9MB = 300 dpi 8x10 B/W image 38MB = high-res color photo.31mb = 256 VGA computer screen Full-Motion Video Storage 120GB = 90-min. movie

24 Recovery Principles Recovery is a Complex Art: Plan for it, Test in Advance Know Your Operating Requirements How much data can you afford to lose? How long can your applications be offline for backup or recovery? How quickly can you recover? Are the capabilities to reverse changes needed? What resources are available for recovery? Can your recovery system reliably respond in the time required? Requires high data integrity, rapid access and performance Source: Strategic Research Corp
