More tests have to be done. I have one of the earliest hard-drive MP3 players, the PhotoTainer. It has a 20GB drive, but also a CompactFlash slot. I did a timing test to see how long the battery would last running songs off both storage media. The battery lasted about 1 hour longer when using the CompactFlash memory card than using the hard drive.
