The particularities of data storing in multilevel data storages under “big data” conditions are considered. For multilevel data storages the task of data blocks optimal allocation with taking in consideration technical characteristics of individual storage levels is formulated. Three models for different variants of data storage types, user requests and expenditures minimization policies are proposed. Methods of solving these problems were proposed. The variant of genetic algorithm to determine the optimal allocation of data blocks onto different levels of data storage is developed.
