Embodiments of the present disclosure relate to a method, electronic device and computer program product for processing data. The method comprises determining a first hotness associated with a first compressed data block stored on a first storage device. The method also comprises: determining, based on the hotness, whether the first compressed data is stored to the second storage device, a type of the second storage device being different from a type of the first storage device. The method further comprises: in response to determining that the first compressed data block is stored to the second storage device, generating, based on a second compression level of the compression algorithm, a second compressed data block from the first compressed data block for storing to the second storage device, wherein the second compression level corresponds to the second storage device.
