My Book Studio Edition ii data accessible if drive is removed?

I currently have a My Book World Edition ii (setup in RAID1).

I know that the data is only accessible from the NAS enlosure as the NAS formats and partitions it in a specific way.

Does the My Book Studio ii do the same or can you access the data if an individual drive is removed and connected directly to a computer?

I believe in RAID 1 that the data is mirrored on the second drive. Basically you are making 2 copies. A RAID 0 drive that is 2T will only be  1T if  setup as RAID 1. In RAID 0 data is on both drives if one goes bad your data is gone. In RAID 1 if one drive goes bad the other has a copy of it. That’s about all I know about it.
