Predictive caching in device for media seek in playback or scrolling

A method of performing predictive caching for media data in a data storage system, the method comprising:

• receiving from a host a seek command associated with playback of a media file, the seek command including a seek interval;
• determining a number of seek points;
• estimating respective logical block address (LBA) ranges corresponding to one or more seek points based on the seek interval;
• determining respective control pages corresponding to the estimated LBA ranges;
• loading the control pages to a buffer in parallel;
• loading data corresponding to the estimated LBA ranges to the buffer in parallel based on the loaded control pages;
• and
• providing the loaded data to the host.

A data storage system comprising:

• a non-volatile memory;
• a buffer;
• and
• a controller means configured to:
• receive from a host a seek command associated with playback of a media file, the seek command including a seek interval;
• determine a number of seek points;
• estimate respective logical block address (LBA) ranges corresponding to one or more seek points based on the seek interval;
• determine respective control pages corresponding to the estimated LBA ranges;
• load the control pages to the buffer in parallel;
• load data corresponding to the estimated LBA ranges to the buffer in parallel based on the loaded control pages;
• and
• provide the loaded data to the host.
