I am thinking of purchasing a Western Digital Raptor 10k HD for my MacPro. I would like to clone my boot drive to it and then use it as the primary boot drive, reformatting the original boot drive to use for storage/backup in drive bay 4. My questions lie with: 1. What size would anyone recommend to get for a boot drive? (My current Boot Drive is only about 65GB full) 2. I have superduper so i should be able to just clone my original boot drive to the Raptor and use it as if nothing has changed, am i correct? Thanks in advance.
