PURPOSE: A hybrid storage device and an operating method thereof are provided to maintain the high performance of I/O(Input/Output) features by locating data blocks on an optimal medium with the consideration of the features of the blocks and media composing the hybrid storage device. CONSTITUTION: First and second storage media(1200,1300) store the data blocks which have the data types divided into hot or cold according to the data types. If the type of the data block stored in the second storage medium is changed, a hybrid controller(1100) duplicates the data block having the changed data type to the first storage medium. If the data type of the data block is re-changed, the hybrid controller omits the reduplication of the data block to the second medium. The first storage medium is an SSD(Solid State Disk) and the second storage medium is an HDD(Hard Disk Drive).
