Are you sure of this?
No. :-) However, I'm willing to count not just the actual disk buffer cache itself, but process-level caching of files. The OP didn't mention what kind of server application he was using, but things like squid and apache will buffer files into RAM (ie, the process' address space).
I am not as sure about things like NFS or Samba/CIFS.
The disk buffer cache from what I have learned is maxed out at 200Mb, which is a small fraction of a 4GB RAM box.
OK. If you've got many hundreds of MBs worth to deal with, perhaps using md(4) would be a better idea.
