As soon as I saw the question I thought it would be contentious. But my default out-of-the-box SQL 2005/2008 model db defaults to 3+1, ie: 4. I set it to a "better" size as part of my config of any new server so I've seen it a fair bit.

But checking our hosted servers and our 2008 Express servers (whose sole purpose is mirror witnessing) which I haven't altered, the sizes remain 3+1.

Now I'm curious about two things:

1) is the model db size determine by OS version, locale, or something else nefarious; and

2) how will this latest QotD biff turn out.

Let me get my popcorn...
