Assigning data for storage based on speed with which data may be retrieved

摘要

A method, system, and apparatus for improving performance when retrieving data from one or more storage media. Files to be stored on the one or more storage media are classified into a ranking of different sets. Differences in retrieval value of different regions of the one or more storage media are exploited by selecting which files to store in which regions. For example, files that have a higher classification are stored in regions with faster retrieval values. The files can be classified based on frequency of access. Thus, files that are more frequently accessed are stored in regions that have a faster retrieval value. The files can be classified by another measure such as priority. For example, the classification for some or all of the files can be based on user-assigned priority. The classification may be based on events or data grouping.

1. A method comprising:
during and in response to a shutdown procedure of a computer system:
storing, at a first memory location, data that is (a) stored at a second memory location and (b) to be used during a next boot up procedure of the computer system;wherein the first memory location is faster than the second memory location;wherein the first memory location and the second memory location are non-volatile memory locations; and during the next boot up procedure of the computer system, accessing the data stored at the first memory location.
