also described in the docs.  

you might be better off splitting the space into smaller chunks.
with that much space in one unit you will be hit hard if any of
it fries -- backups or not.  do you have any files that really
take up 325G?  if not you could split the space into multiple
128GB sections for separate use.  makes backups a whole lot 
easier...  let alone restores.
