Answer 4—Speech requires between 1.1 (compressed) and 28.8 (uncompressed) MB per hour. A 20-GB disk would give playing times between 700 and 18,000 hours, or more than two years of compressed speech!

Music requires between 60 and 635 MB per hour, giving playing times of 30 to more than 300 hours. Video requires between 2.7 and 135 GB per hour, giving playing times of 8 min. to 7.4 hours on a 20-GB disk.
