PROBLEM TO BE SOLVED: To prevent the deterioration of efficiency of write cache processing in a write control method and a storage device. SOLUTION: This write control method in a storage device for controlling write to a recording medium has: a plurality of data areas in which data are written; a plurality of alternate areas set correspondingly to each data area in which data to be written in the plurality of data areas are written by alternate processing; and at least one management area in which alternate processing information for managing the alternate areas is stored by using write cache processing. The method also includes: confirming the number of use of the alternate areas or the use rate of the alternate areas in each data area on the basis of the alternate processing information; and setting the write cache processing with respect to the arbitrary data area in a disable state when the number of alternation or the use rate of the alternate areas in an arbitrary data area in which the data instructed by the data write instruction are to be written is a specific value or more (S4).
