Abstract: Embodiments of the present disclosure provide a DRAM-based storage caching method for a smart terminal, and the method includes: capturing an IO delivered by an upper-layer application; determining, based on a configuration policy, whether the IO belongs to a pre-specified to-be-cached IO type; and when the IO belongs to the pre-specified to-be-cached IO type, performing a corresponding caching operation for the IO in a DRAM disk based on a read/write type of the IO and a preset caching policy, where the DRAM disk is a block device created by using a reserved part of DRAM space of an operating system.
