Use by a host device having a first file system of a portable storage device having a second file system and supporting file segmentation

摘要

A host device includes a first file system, and a storage device includes a plurality of memory units and a plurality of controllers. While the host device is operative coupled to the storage device, the host device creates a second file system corresponding to the storage device and copies host content from the first file system to the second file system. The second file system is segmented into a plurality of segments, each of the plurality of segments being uniquely associated with a particular one of the plurality of controllers. The host device selects a data transfer rate to write the host content from the second file system to the storage device.
