Abstract: A storage device and a data storing method thereof are provided. The storage device includes a data storage medium and the control unit. The data storage medium includes a data storage area with a plurality of first type of data blocks. When a data reading operation is executed on a current data block of the data storage medium, the control unit determines whether a read count of the current data block is greater than a first threshold, determines whether the current data block is one of the first type of data blocks and generate a determination result according to the result, the control unit selects a plurality of first type of data blocks and switches the selected data blocks to a fast mode. Finally, the control unit moves data stored in the current data block to the selected data blocks under fast mode.

Abstract: An exemplary embodiment provides a data storage device including a flash memory and a controller. The flash memory includes a plurality of chips, each of the chips includes a plurality of pages, the pages are arranged to assemble into a super block, the pages of the super block are numbered 0˜X from top to bottom of the super block, the pages with number 0˜Y?1 constitute a data area, and the pages with numbers Y˜X constitute a RAID parity area. The controller corrects data of the data area according to data of the RAID parity area when the data in the data area cannot be successfully read.
