Problems solved by technology

Moreover, when purchasing storage media, it is often only possible to purchase the current high-priced storage media along with the development of storage media.
Therefore, there is no flexibility in the use of storage media, and the storage capacity of the storage media cannot be adjusted according to user needs.

Abstract

The present invention provides a kind of micro-flash disk (Mini Flash Disk) that guarantees data security, has a casing that conforms to the hard disk standard specification specified by International Organization Technical Committee T13, the size is 2.5 inches or 1.8 inches in width, and on the casing There is a control chip connected to the external connection port, and at least two connection units connected to the control chip and having the same interface specification. The connection units can be connected to a flash memory device respectively, so that the control chip can store data in the first flash memory. The data in the device is mirrored to the second flash memory device to ensure the security of the data in the micro flash disk.

Description

technical field [0001] The invention relates to a micro-flash disk, in particular to a micro-flash disk which can ensure the safety of memory data. Background technique [0002] At present, traditional hard disks are usually accessed mechanically. Therefore, in environments with a lot of vibration or high humidity, the mechanical access method of the disk is prone to problems such as damage or failure of reading and writing. In view of the advantages of high stability, shock resistance, moisture resistance and high transmission speed, flash memory has been used to replace the magnetic disk in the traditional hard disk, and a storage medium called flash disk (Flash Disk) has been developed. [0003] Such as figure 1 As shown, the micro-flash disk 10 is mainly composed of three major components including an integrated disk electronics (IDE) interface 12 , a control chip 14 and a flash memory 16 . Flash memory has a limited lifetime and usually only guarantees 100,000 writes....
