Abstract

The invention discloses a data exchange system of a storage device, comprising a data processor and a storage device, wherein the data processor is mutually connected and exchanges data with the storage device. The storage device comprises a controller, a caching unit, at least one connecting port arranged on the controller and at least one storage unit. The storage unit is mutually connected with the controller through the connecting port. The caching unit is mutually connected with the controller and used for caching the driving program of the storage device and marking the address information list of the storage space of the storage device, thereby the data processor can carry out addressing on the whole storage space without accessing every storage unit, and the storage unit in an idle state can disconnect power supply so as to achieve beneficial effects of power saving and loss reduction of the storage device.

Description

technical field [0001] The invention relates to a storage device and a data exchange system using the storage device. Background technique [0002] With the rapid development and widespread popularization of electronic computer technology, the functions of electronic computers are becoming more and more powerful, and the amount of data that needs to be processed is increasing day by day. Therefore, electronic computers have higher and higher requirements on the capacity of storage devices. [0003] In the prior art, a plurality of independent magnetic disks are mainly connected through a control chip, which is simulated as a large storage device to expand the space of the storage device. The total capacity of the storage device is the sum of the capacities of all single disks, and when the capacity of the first disk is used up, the data is then stored in the second disk, and so on. Because the address information of each disk is recorded separately at the beginning of the ...
