    Abstract: In a data management method for a storage device, the storage device includes a nonvolatile memory device including a plurality of memory blocks. A TRIM-after-COPY command is received from an external host such that a data compaction operation is performed on a first storage region. Valid data stored in the first storage region are internally copied into a second storage region based on the TRIM-after-COPY command. A TRIM operation is performed based on the TRIM-after-COPY command to update a logical-to-physical address mapping table and a valid page bitmap.

    Abstract: A computing system includes a storage device, and a host device configured to flush a plurality of pages to the storage device. The host device includes a write-back (WB) cache configured to store the pages, and a file system module configured to flush pages having first characteristics to the storage device from among the pages stored in the WB cache, and then flush pages having second characteristics which are different from the first characteristics to the storage device from among the pages stored in the WB cache.

    Abstract: A storage device, a directory entry lookup method for the storage device, and a host running the method can provide a quick directory entry lookup. The host includes an interface for exchanging data with the storage device which stores a multi-level hash table comprising directory entries of each directory, and a file system module receiving a file lookup command designating a target directory and a target filename, calculating a hash value which reflects the target filename and a lookup level, and searching for a directory entry which comprises the target filename in a bucket corresponding to the hash value from among buckets at the lookup level which are included in a multi-level hash table of the target directory. If the search for the directory entry fails, the file system module increases the lookup level and again calculates the hash value and searches for the directory entry for the target filename.
