Data Storage Device and Data Management Method Thereof

A data storage device, which is coupled to a host, comprising:

• a storage media having a plurality of data sectors for storing a media file, wherein the media file having a plurality of logical address windows is stored into the data sectors with sequential logical addresses;
• and
• a controller coupled to the storage media for receiving a first read command and a first logical address which is corresponding to the first read command from the host, determining whether the first logical address is located in a first logical address window of the logical address windows, activating a timer and a counter when the first logical address is located in the first logical address window, reading a plurality of first data sectors from the storage media according to the first logical address, outputting data of the first data sectors to the host, obtaining a valid duration calculated by the timer and the number of the first data sectors counted by the counter when any logical address corresponding to the first data sectors is outside of the first logical address window, calculating an average data throughput according to the number of the first data sectors and the valid duration, and determining whether the average data throughput exceeds a predetermined threshold,
• wherein the controller performs a blocking procedure to prevent the storage media from being accessed when the average data throughput exceeds the predetermined threshold.
