Method of Interfacing A Host Operating Through A Logical Address Space With A Direct File STorage Medium

A method of transferring data between a host system and a re-programmable non-volatile mass storage system, the method comprising:

• receiving data associated with addresses in a logical block address (LBA) format at the mass storage system from the host system;
• selecting, based on information from the host system, a correlation method to determine a correlation of received data to host system application files;
• determining a correlation of a group of the received data to a host system application file;
• and
• mapping LBA addresses for the group of data to offset addresses within a data object identified by the unique filename.

A method of transferring data between a host system and a re-programmable non-volatile mass storage system, the method comprising:

• receiving data associated with addresses in a logical block address (LBA) format at the mass storage system from the host system;
• determining if there is a correlation of a group of the received data to a host system application file;
• assigning a unique file name to the group of the received data if the correlation is determined and mapping LBA addresses for the group of data to the unique file name and a data offset;
• and
• assigning the unique file name to a contiguous range of LBA addresses in the received data if the correlation is not determined and mapping the contiguous range of LBA addresses to the unique file name and a data offset.

A method of transferring data between a host system and a re-programmable non-volatile mass storage system, the method comprising:

• determining if the host system is configured to provide host system file identifiers prior to writing logical block address (LBA) format data, wherein the host system file identifiers indicate a correlation of subsequently transmitted LBA data to application files on the host system;
• if the host system is configured to provide host system file identifiers, then:
• receiving a host system file identifier;
• receiving a group of data associated with addresses in a logical block address (LBA) format from the host system and with the host system file identifier;
• mapping the host system file identifier to a unique file name;
• and
• mapping LBA addresses for the received data to offset addresses in a data object identified by a unique filename;
• and
• if the host system is not configured to provide host system file identifiers, then:
• automatically correlating received LBA format data to application files on the host system without host system file identifiers;
• assigning a unique filename to a group of received data determined to correlate to an application file;
• and
• mapping LBA addresses for the received data to offset addresses in a data object identified by a unique filename.
