Thanks Dingo and geofelt.
I have another internal HD for backing up all my data. The RAID 0 setup is for photo/video edits. And then I have a 3TB hard drive to back up all the work.
Copying/Pasting does seem faster and so I presume that the Raid 0 is working as intended...
Thanks again everyone for the inpouring of all the responses in such a short span of time.
I consider this topic solved and closed!
Very friendly community so far
