Can 2 daisychained drives, each configured in RAID 0 be combined in a RAID 1 array using Disk Utility?

You can combine two RAID0 Duo's into a RAID 10 array for redundancy. According to WD, because of the two channel Thunderbolt (not to be confused with two Thunderbolt ports), if you daisy chain two of these in one RAID0 set, you'll see a significant increase in performance. In a single RAID0 Duo, it is writing to both of the internal drives simultaneously, doubling the speed. So if you have two channels, and two Duo's, it makes since that the speed would double again. It is writing to four drives at once, hence 4x the speed -- in theory.
