Data Storage 

DRAFT

What is needed

• On board (Terabytes)

• Interface for data return (Terabytes)

Technology Goals

• On-board storage of 1 Terabyte available in 1999 on a “3480-size” cartridge, also will be available on a 14” platter in 2002; 5-10 Terabytes by 2005

• Storage systems that can operate in near vacuum

• Cost effectiveness

Today’s State of the Art

• For more details, please see Appendix D

• Storage Capacities range from a few gigabytes to several hundred. Some examples are:

  • DLT7000 - 35GB, SuperDLT tapes 100-500GB,
  • Optical disk drives can hold up to 1 Terabyte but are currently cost prohibitive.
  • Hard disks can hold 18 GB each and can be stacked; currently not cost effective.
