So I've been considering getting a Velociraptor WD Hard Drive or an SSD and while the appeal of getting a crazy fast Hard Drive is an obvious choice from simple cool factor and my basic comprehension that "Faster is better" and "faster read speed means faster load times" but I'm curious to know more rather than the sound bytes I've heard from my other friends who build computers.
I understand that SSD > Fast Mechanical HD because there are no moving parts and so there is "theoretically" no scan time.
How much improvement could I expect going from a standard 7200RMP HD to say a 10,000RMP HD or an SSD
Would I see just faster load bars, or things like faster and farther away loading of textures and NPCs?
Would games would launch faster if they were installed on this faster drive?
Are there any benefits that I'm overlooking in my inexperience with these "performance hard drives"?
