Chapter 25. Listening to Digital Music: ... > Features and Considerations

Features and Considerations

When purchasing an MP3 player, one of the primary considerations is the amount of storage space you’ll need for your files. MP3 players are available with everything from just 32MB of internal flash memory up to 20GB or more of internal hard drive storage. This is one of the main drivers of their price. The more you pay, the more disk space you’ll be able to purchase for your music.

Other features to look for include battery life, the amount of skip protection, the number and type of accessories provided, and the ability to store data and use the device as a backup hard disk. The Apple iPod, for example, offers up to 10 hours of battery life when used for continuous playback. In terms of skip protection, the iPod has up to 20 minutes of skip protection provided via a 32MB solid-state memory cache. This means that if you’re walking or running, or the device is generally being bumped around, your music will play seamlessly because it’s buffered in memory rather than being read in real time from the hard disk.
