Exchange 2010 dumpster without Single Item Recovery Enabled

I understand how the dumpster works with Single Item Recovery Enabled.

Can anyone point me to a Microsoft Article that explains what feature are available with it disabled?

Do I only get the following features?

Store Soft Delete - this is when an item has been deleted from the Deleted Items folder and placed within dumpster.
Store Hard Delete - This is when an item has been marked for purging out of the store.
Hard Delete via Outlook (Shift-Delete) - This is when the end user performs a shift-delete on an item. This results in the item bypassing the deleted items folder and being directly placed in dumpster.

Also with Single Item Recovery Disabled does Litigation Hold still work the same way?

Thanks
