I"m planning to split my 74gig raptor into 2. 1 for OS itself and others are for datas and school assignment. Would it be a good choice to partion it? Do I lose/gain any perforamce on it? This is my first time having a raptor drive, so I don't know much about it. By the way I use Partitionmagic to do the job. Any input/comment is welcome. Thank you.
