PROBLEM TO BE SOLVED: To provide technology for performing data transfer between storage devices in more proper timing.SOLUTION: In an information processor, the number of accesses to a block 31 is counted for each sub block 31a dividing the block 31, by using an access number count table 214a. A sub block address value representing an address of the sub block 31a in which the number of accesses has reached a threshold value W or greater and time when the number of accesses has reached the threshold value W or greater are stored in one entry of an address/time recording table 214b. By correlation analysis between the sub block address value and the time, the information processor detects a sequential access, specifies the block 31 to be transferred to an SSD (Solid State Drive) and a deadline that is time when the transfer of the block 31 has to be ended, and performs scheduling so as to transfer the specified block 31 until the deadline. |
