Abstract: Provided are a method and a system for transmitting data between storage devices over peer-to-peer (P2P) connections of peripheral component interconnect-express (PCIe). The method, performed when a first storage device receives a data request from a host, includes caching data of another storage device via PCIe connection in response to the data request, and transmitting the cached data to the host. The first storage device is configured to convert a logical address received with the data request to a physical address of a memory region of a second storage device, to store data transmitted from the second storage device via the PCIe connection in a second data cache according to the converted physical address, and to perform a cache replacement scheme for the data stored in the second data cache.
