You know, I read an article about comparing NTFS (windows file format) and HFS+ (OS X format).
Disk Caching is important, but there are other things to consider as well. Fragmentation is a big issue. I know my Windows XP machine has to get defragmented every couple of days, but it is not an issue on OS X 10.3 due to the OS's built-in defragmentation of files used often. If I find the article I'll post it. It was techie but interesting on how caching and file systems work.


Does this matter with temp files? Perhaps. Is it likely that when you are using Finale on Windows that it is keeping all the temp files in memory? Probably not. I see my little hard drive light go on all the time with Finale. I'm sure that there is some sort of Windows tool out there that one can run if you really want to find out what is going on in the cache.

Well, on Windows, files that are often opened and written to disk (as temp files are) will likely be read from and written to RAM because of the built-in disk caching that Windows has offered for well over a decade.

Indeed, without that disk caching, Windows would be unusable (I've experimented with turning it off in earlier versions of Windows and it bogs things down to the point of complete unusability; even on systems with small amounts of RAM, the RAM allocated to the disk cache actually improves performance dramatically).

I'd be surprised if a modern OS like OS X did not have sophisticated disk caching built in and turned on that would have more benefit than the same amount of RAM dedicated to a RAM disk.
