What is HyperDuo?
https://en.wikipedia.org/wiki/Hybrid_array
HyperDuo  is  a  technology  created  by  Marvell  Semiconductor ,  Inc.  to 
optimize  the  performance  of  storage  technology.  This  technology  is 
built  in  to  the  UGT
-ST644R  card.  It  involves  the  combination  of  SSD 
as  cache  storage  for  the  HDD  drive  to  give  unparalleled  access  speed. 
This  tiering  of  SSD  and  HDD  can  give  you  80%  SSD  performance  at 
about  the  a  third  of  the  cost.  Using  safe  mode,  you  mirror  frequently 
access (hot files) in SSD speed and in Capacity mode, you combination
SSD  and  HDD  together  with  frequently  access  (hot  files)  in  the  SSD. 
You  can  easily  setup  the  configuration  in  the  card  BIOS  to  optimize 
your system.
Minimum Requirement: one SSD and one HDD.
It can be setup in two modes of operation.
