Embodiments of the present disclosure provide a data storage method, an electronic device, and a computer program product. The method includes: determining the number of at least one first storage apparatus of a storage system, each first storage apparatus being persistent and storing a log that includes record entries of to-be-stored data; and writing, if it is determined that the number is greater than a threshold number, the to-be-stored data into a corresponding memory table from the log where the to-be-stored data is located, wherein data in the memory table will be written to a second storage apparatus of the storage system. In this way, the storage efficiency of the storage system can be improved.
