The invention discloses methods and a system for storing and obtaining data, wherein the method for storing data includes the steps of: writting the data inputted by a host into a solid hard disk array; comparing whether the current data size of the solid hard disk array is larger than or is equal to a preset threshold value; and if so, transferring the data of the solid hard disk array into a local hard disc. The method for obtaining data includes the steps of: judging whether the solid hard disk array currently stores the required data or not; and if not, obtaining the required data from the local hard disc, or if so, obtaining the required data from the solid hard disk array. The embodiment of the invention guarantees that the data can not be easily lost, and reduces the complicated degree of a storage system.
