The Rio Riot was a hard disk-based "jukebox" MP3 digital audio player produced by Diamond Multimedia as part of the Rio line.
It shipped in March 2002, and was an early competitor to the Apple iPod, coming out some four months after its release.
[1] Critical reviews of the Riot were mixed, with many describing it as a good device in its own right, but one that fell short of the iPod.
[1] Reviewers praised its generally strong hardware and large storage;[2] however, they panned its large size[3] and slow USB transfer rates,[4], especially relative to the iPod's FireWire connection.
One Rio Riot is held by the Computer History Museum in Mountain View, California.
