The raptor hard drive will be faster but thats is not the real befit from having two hard drives. If you use the raptor for your programs and applications and then 500 gig for you data if and when you have to reinstall your os you wont lose all that information. That, however, is not a reason to have a solid data backup plan. But i'd say 95% of the time you just need to reinstall the os and the problem is not due to a bad hard drive.
