We have not looked at the update directories for WSUS version 3 on SBS in a while.
This evening we are completing an SBS Swing and got the chance to size them up ... and they are large ... in the order of 40GB large.
The size of the update directories are definitely something to keep in mind when evaluating an older SBS box for WSUS 2.x or 3.x or an in-place upgrade to SBS R2.
With the advent of Office 2007, Windows Vista, and soon Windows Server 2008 we can probably expect to see WSUS update directories into the 100GB+ magnitude.
That is definitely something to keep in mind when future planning a server configuration.
