Resolved how to prevent yosemite from creating fusion drive on new rMBP mid 2014

-

i got new rmbp , came mavericks. first thing did run diagnostic test no problems found next erased entire hd. (i been using yosemite since beta , pretty use now, figured install did on old mbp)

wanted create recover hd wait till recovery partition creator updates foe yosemite.

after booted , installed apps , decided repair permissions disk utility enabled disk utility debug menu selected show every partition

, found

macintosh
efi (hidden)
macintosh (hidden)
recovery hd (hidden)

thought made mistake erased again (firewire through old mbp)
checked diskutil corestorage list
came "no corestorage logical volume groups found"

re-did installation of yosemite , again when booted created hidden macintosh , recovery hd. recovery hd doesn't show @ boot when hold down option key. ran diskutil corestorage list , there again

how stop creating fusion drive automatically? have 1 1tb ssd, why create logical volume? , how stop it?

can share thoughts on this?
 

maybe not understanding or not, fusion drive requires 2 drives. not making fusion drive.
