Extendable mobile hard disk

Abstract

The invention discloses an extendable mobile hard disk. The extendable mobile hard disk comprises a housing (1), and a control circuit board (2) and a memory interface both arranged on the housing (1), wherein the control circuit board (2) comprises an internal memory (3); the extendable mobile hard disk further comprises an extension interface (5) and an independent hard disk (6) which are arranged on the surface of the housing (1), wherein the extension interface (5) is connected with the control circuit board (2); when the independent hard disk (6) is connected with the extension interface (5), the internal memory of the independent hard disk (6) and the internal memory of the internal memory (3) both are used for storage under the control of the control circuit board (2); when the independent hard disk (6) is disconnected from the extension interface (5), the internal memory of the independent hard disk (6) is independently used for storage. The extendable mobile hard disk can be reasonably extended in internal memory according to a data size, has flexible extendability, and further is capable of improving the safety of data transmission, and therefore, the extendable mobile hard disk is more convenient for a user to use.

Description

technical field [0001] The invention relates to an expansion-based mobile hard disk, which belongs to the technical field of storage devices. Background technique [0002] With the continuous development of electronic equipment, more and more fields rely on electronic equipment for daily management and execution. When electronic equipment is used in daily life, relevant data will be generated. When storing data, it can usually be Use the storage module carried in the device itself. And when data needs to be saved or backed up, it is usually necessary to use a mobile hard disk. Mobile hard disk is a storage product with hard disk as storage medium, exchanging large-capacity data between computers, and emphasizing portability. It usually includes a casing, a control circuit board, and a storage interface. The control circuit board includes memory storage, and the control circuit in the casing is used The board controls the memory usage. After the storage interface is connect...

AI Technical Summary

Problems solved by technology

However, such a storage medium still has some problems in the actual use process. Since this form of hard disk memory is fixed, and if the data is large, the storage of data cannot be satisfied, and only a hard disk with a larger memory can be replaced. The existing mobile hard disk does not have scalability, the memory is relatively fixed, and the available capacity of the hard disk cannot be flexibly adjusted according to the size of the data, resulting in limitations in the use of mobile hard disks
