Ok, I have no clue how hard drives operate. Honestly, it's the least interesting part of my system, so I never bothered to explore the technology. But I've got this idea in my head that just won't go away.
Doubling up on everything seems to be really popular these days in computer technology. We've got dual-core CPUs, hyperthreaded cores, dual vertex shaders, SLI (ok, that one is pretty much dead now), etc.
So why can't a HDD manufacturer implement a single hard drive that functions as a Raid 0 array. Don't HDDs have multiple platters to begin with? Couldn't these platters be assigned to striping duty? I would think this would be an ideal solution to better HDD performance. A fast HDD system in a single unit (for better performance and lower costs).
Somebody explain the problems with this to me.
