1. Suppose you use about 500 GB (0.5 TB) of storage in your personal system, filling about two-thirds of its 750 GB disk. Most of that storage is used by your video library. Photos, music, and software (including the operating system) use about 20 GB.

Traditional data files, such as word processing files, spreadsheets, and e-mail, require less than 1 GB. Which of the technologies and strategies discussed in this case might be of practical value to you? Why?

2. Both SAN and NAS systems can use RAID internally (see discussion earlier in this chapter). Why might this be a good idea?
