Embodiments of the invention disclose a virtual storage method, virtual storage equipment and a virtual storage system for terminals. The method comprises the following steps: when a terminal is started and powered on and starts loading an external memory card, the terminal sends a virtual storage request signaling to a cloud storage server through a dedicated channel carried by a high-speed wireless network; the terminal receives authentication success information sent by the cloud storage server through the dedicated channel, and sends an authorization request to the cloud storage server through the dedicated channel according to the authentication success information; after receiving authorization information sent by the cloud storage server through the dedicated channel, the terminal carries out a virtual disk mapping operation on a storage space corresponding to the terminal in the cloud storage server to map the storage space into a local virtual disk of the terminal; and the terminal loads applications and data corresponding to the terminal from the storage space corresponding to the terminal in the cloud storage server according to the mapping relationship between the local virtual disk of the terminal and the storage space corresponding to the terminal in the cloud storage server.
