Abstract
Embodiments of the present disclosure relate to a method, a device, and a computer program product for storing data. The method includes determining multiple access frequencies and multiple input/output (IO) modes of multiple data blocks, where the multiple data blocks are stored in a disk, and an IO mode in the multiple IO modes indicates an access size, a read operation proportion, and a sequential access proportion. The method further includes determining multiple cache hit ratios corresponding to the multiple IO modes. The method further includes determining multiple scores of the multiple data blocks based on the multiple access frequencies and the multiple cache hit ratios. In addition, the method further includes determining, based on the multiple scores of the multiple data blocks, a data block in the multiple data blocks to be replicated to a cache.
