Yes.  I use Farstone Virtual Hard Drive Pro (a very stupid product name
if you ask me, but there you go) and the results are below.  I am
guessing the bulk of the difference is due to this being formatted NTFS
not FAT.  Frankly having a FAT formatted ramdisk seems like a big waste
of memory as with NTFS you can enable compression on the whole volume,
though oddly even when you do that the VOLUME_IS_COMPRESSED flag is
still FALSE.
