RapidShare is one of the world's largest file-hosting sites, with 10 petabytes of files on its servers, and handling up to three million users simultaneously. Upon uploading, the user is supplied with a unique download URL which enables anyone with whom the uploader shares the URL to download the file. No user is allowed to search the server for content. Registration and payment allow benefits such as unlimited download speed, immediate download (instead of experiencing a waiting period), download of several files simultaneously, queue skipping, the facility to interrupt and re-start downloads, uploading and downloading bigger files up to 2 GB, allowing Free Users to download their files with Premium privileges ( TrafficShare ) and to store up to 50 GB of data that cannot expire. Registration required.
