SharePoint Dragons

If you create a content database via the SCA UI (Application Management > Manage content databases> Add a content database), not only are the Autogrowth settings of your Model DB ignored, SharePoint also ignores the Initial Size of the Model Log files, and instead takes divides the size of your Data file by 4. So, if your data file is 100 GB, the Initial Size of your Log files becomes 25 GB.
