So, looking further into 'new' storemi (sorry I should have replied earlier) it appears that AMD have gone to more of a cache route instead of real storage auto-tiering. It is therefore junk. Performance will be lacking as write will always be to the lower tier and is therefore junk. I wouldn't recommend using it. Either get a copy of the old Storemi or pay Enmotus.
I think some people that don't understand storage have got in the ear of someone important that also doesn't understand storage unfortunately. Either that or Enmotus started asking too much money for their product.
Either way Storemi is dead and probably won't even make it to all platforms.
Shame...
