File system having variable logical storage block size

A system comprising:

• a processor;
• a data storage device having memory storage accessible by the processor;
• filesystem code executable by the processor to manage files on the data storage device, where the filesystem code is executable to manage files on the data storage device using storage areas of a first type having a first logical storage block size and storage areas of a second type having a second logical storage block size that differs in size from the first logical storage block size, where the first and second logical storage block sizes are used by the filesystem code to logically divide the memory of the storage device, and where the filesystem code is further executable to store file data of a file of a first file type in storage areas of the first type and file data of a file of a second file type in storage areas of the second type, and where the filesystem code is executable to identify whether each file managed by the file system code is of the first or second file type.
