"ContigFileAllocSize" value info help?

Does someone know an optimized value for this registry key?

HKLM\SYSTEM\CurrentControlSet\Control\FileSystem\
"ContigFileAllocSize"

The articles I get via search all say 512. The thing is, all of them were written in 2003 or even earlier. Likely the optimization is irrelevant now.

The setting appears to date back to Windows 95, Windows 98 and the FAT32 file system. The only references to a value are a decade or more old and on sites of questionable reliability. I doubt that modern versions of Windows even look at this value. The value does not exist by default in XP or Windows 7. The safest thing to do would be to omit the value and let Windows use the default. But I doubt it is valid anyway.
