AndyC, I am not savvy in Windows internals, in how it caches and manages file O/I. I came across this old article mentioning an anecdotal evidence of how people were able to significantly increase their Photoshop productivity with ramdisk

Can you please elaborate on your point why "it won't ever be faster"? Please explain how is HDD I/O not holding up applications under no circumstances in WinXP for instance? I understand there is RAM caching of all file I/O in any modern OS, but is there no such use case when ramdisk really helps? I'm just confused by categorical "it won't ever be faster" and the article I referred to above.

Anyone who understands subject matter please share your knowledge.
