AI Technical Summary
Technical Problem
In the case of data storage devices connected to multiple host devices, the data transmission and reception speeds are low, resulting in limitations in the host device in improving data processing performance.
Method used
By introducing an auxiliary storage device into the data storage device, snapshot operations of data stored in the data storage device used by a plurality of host devices are independently performed, thereby avoiding communication delays with the host device and the data storage device.
Benefits of technology
Effectively manage snapshot data, improve the data processing performance of multiple host devices, and reduce communication delays between host devices and data storage devices.

Abstract
The invention relates to a data storage device, a data storage system and a computing system. In an embodiment of the disclosed technology, a data storage device includes: at least one memory device including a plurality of memory regions configured to store data; a first controller configured to allocate a plurality of memory regions according to memory allocation requests of one or more host devices; and a second controller configured to: in response to a snapshot request of a first host device among the one or more host devices, generate snapshot data corresponding to at least a portion of data stored in at least a portion of the plurality of memory regions allocated to the first host device; and store the snapshot data in an auxiliary storage device coupled with the second controller.
