Abstract: A multimedia storage system includes a multimedia distribution device and a plurality of storage devices. The multimedia distribution device splits a multimedia file into a plurality of multimedia segments and monitors the operation statuses of the storage devices. The multimedia distribution device further configures each of the multimedia segments to be stored in at least two of the storage devices according to the available storage devices in the multimedia storage system. The storage device comprises a network access device for receiving the multimedia segments and a redundant array of inexpensive disks for storing the received multimedia segments.
