I believe you, I just haven't run into this myself and I guess it is correct that YMMV depending upon setup then. All of my WD Green drives are sitting in a Linux server and exposed as samba shares to various computers (including some running Windows 7) and HTPC devices. My guess would be that this setup results in greedier read-ahead caching by the local OS because of the relative slowness and unreliability of accessing blocks via a network-share file versus what the OS considers to be a local file.
