Use the internet to find quoted prices, capacities, and performance of the following memory / storage devices:
  1. DDR RAM
  2. Rambus RAM
  3. Flash Memory
  4. Hard Drive, personal use (e.g. Seagate Barracuda)
  5. Hard Drive, enterprise use (e.g. Seagate Cheetah)
  6. CD-RW
  7. DVD-RW
  8. Tape Backup
For some of these devices, you need to distinguish between the media cost (the tape only) and the device cost (tape reader).
Plot your results in a graph with axes for the random access times, the capacity, and the cost per B. Each axis should use logarithmic scale.
In preparation for the next homework:
Go to the web site of Jim Gray, Microsoft Research. Download the article on Windows 2000 Disk IO Performance and understand how he measures performance.
