File System For Storing Files In Multiple Different Data Storage Media

A host system comprising:

• a file system;
• and
• a processor for executing the file system, wherein the file system stores a first file in a first data storage medium based on an intrinsic value of the first file, the file system stores a second file in a second data storage medium based on an intrinsic value of the second file, and the file system dynamically moves the second file from the second data storage medium to the first data storage medium in response to a change in the intrinsic value of the second file, wherein the first and the second data storage media are different types of data storage media.

A host system that comprises code for storing portions of a file on multiple different types of data storage media, wherein the code is stored in a computer readable medium in the host system, the host system comprising:

• code for allocating a first portion of a file for storage in a first data storage medium and a second portion of the file for storage in a second data storage medium using a file system based on intrinsic values of the first and the second portions of the file, wherein the first and the second data storage media are different types of data storage media;
• and
• code for dynamically moving the first portion of the file from the first data storage medium to the second data storage medium using the file system in response to a change in the intrinsic value of the first portion of the file.
