> NTFS is in fact effectively an in-memory filesystem when you have caching, and not going out to disk to satisfy various requests.

It is interesting to see that NTFS is doing extremely well in a few different tests that are entirely satisfied from the cache: the list directory operation and the cached read/write operations. OTOH it does not do as well in tests that could potentially be satisfied from cache (like file open tests).

In any case I intend to retry the tests using NTFS on a RAM disk when I get some time.
