Apparatus and system for copying data to multiple memory media, and copying method thereof

Abstract

A device for replicating data for a plurality of storage media, a system and a replication method thereof are provided, which solve the problems of limited connectable target storage devices, slow transmission brought by limited bandwidth, and the simultaneous limited replication process number by system resources in an existing replication mode. The invention provides a cascade mode based on a USB interface, which modifies a USB slave computer in which the target storage medium is located, and realizes one-to-many data replication through connecting a plurality of slave computers in serial. The invention is provided with a USB HOST unit in the inner structure of an existing slave computer, and adds a cascade control logic unit between a USB Device unit and the USB Host unit, wherein the USB Device unit of each slave device is connected with the USB Host unit of an upper slave computer or the host computer, the USB Host unit of the slave computer is connected with the USB Device of the lower slave computer, and the cascade control logic unit is used to connect the USB Device unit and the USB Host unit.

Description

technical field The invention relates to USB technology, in particular to a device, system and method for duplicating data to multiple storage media. Background technique In some application scenarios, a large amount of data needs to be copied to multiple storage media (including hard disks, optical disks, flash memory, etc.). For example, computers with pre-installed operating systems leave the factory, audio and video media are distributed to different places, software installation CDs are produced in batches, and so on. The time required for the copying process depends on the amount of data to be copied and the number of target storage media to be copied. At present, a method for copying a large amount of source data to multiple target storage media is: USB (Universal Serial Bus, Universal Serial Bus), IDE (Integrated Device Electronics, a transmission interface of a hard disk), SATA (Serial The abbreviation of ATA, that is, serial ATA), SCSI (Small Computer System Int...

AI Technical Summary

Problems solved by technology

The technical problem to be solved by the present invention is to provide a device, system and copying method for copying data to multiple storage media, so as to solve the problem of slow transmission and system resources caused by limited connected target storage devices and limited bandwidth in the current copying method. An issue that limited the number of simultaneous copy processes
