The embodiment of the invention provides a data storage method, an electronic device and a machine readable storage medium. The method comprises: the electronic device acquiring first data needing tobe written into the data table, obtaining a fingerprint calculation template corresponding to a data source of the first data, and calculating a first fingerprint of the first data according to the fingerprint calculation template and the first data, searching a second fingerprint of the second data from the data source from the duplicate checking table according to the data source, judging whether the searched second fingerprint is the same as the first fingerprint or not, and deleting the first data if the searched second fingerprint is the same as the first fingerprint. Thus, rapid duplicate checking, duplicate removal and storage of the data can be realized based on the duplicate checking table. In the duplicate checking process, the data table does not need to be queried. Indexes do not need to be established for different data sources on the data table to increase the speed of querying the data table. The problem that the writing performance of the data table is poor due to the fact that multiple indexes on the data table are dynamically maintained is solved, and the physical space occupied by the indexes on the data table and the maintenance expenditure are saved.
