The Personal Terabyte Project

Magnetic disk drives are increasing in capacity at a rate of over 60% per year, and dropping in price at a similar rate. Manufacturers expect these trends to continue for at least a decade. In five to eight years, magnetic disks will hold a terabyte of data. In approximately ten years, the price of a terabyte of disk storage should drop to a few hundred dollars, putting a terabyte of storage into a typical home. We call this system a Personal Terabyte.
The Personal Terabyte Project at Georgia Tech is developing a set of tools for managing and exploiting this massive personal data repository.

Overview of Personal Terabyte Project: pdf file or postscript

Our research to date focuses on three main areas:

1. Prefetching World Wide Web Data to avoid network delays
2. Prefetching Blocks from Disk to Memory to avoid page fault penalties
3. Backup and Reliability to protect against site disasters and accidentally-deleted files

Other important research issues related to the personal terabyte include:

1. Future disk architectures: network-attached disks, intelligent disks, ...
2. File system organization for the Personal Terabyte
3. Indexing and Searching the Personal Terabyte
