I am seeing the same thing with the latest Speccy (1.29).
My primary disk-drive is a 6Gb/second SSD. See below.
My motherboard is an MSI, with built-in RAID support.
My secondary disk-drive is a 'RAID-1' pair of Seagate 500GB drives.
The volume-serial-number for the RAID set is showing the same as the SSD disk,
and the SMART data is for the OCZ.
