Is Samsung's Magician software necessary to be able to use the Samsung 840 Pro SSDs? What functionality exactly does the Magician software provide? I want to set up two 840 Pro drives in RAID 0, along the lines described in Anand's article from August 2012, only using 840s instead of the 830s used in the article. On the website I see Magician software (version 3.2 or 4.0) and Data Migration Tool (version 1.0 or 1.1), as well as a driver. I don't see any manuals online or clear descriptions of what the Magician functions are. The Samsung website also warns that after Magician is engaged the SSD will not be recognized if it is part of a RAID array, which would seem to be a reason to NOT want to install the software in my situation.
