Would you really use a 5400 RPM drive? Sure the noise is alot less, but your performance suffers a great deal. your seek time goes to hell too. The whole reason people buy 15k RPM drives is becuase they fast as hell.When your disk spins faster you can pick up the data faster. If you miss a spot, the disk spins back around faster to get back to that spot.
The reason HD's haven't been making big jumps is because HD manufacturers seem to have hit a brick wall when it comes to drive density. Currently most hard drives hold 20 gb/ platter. This seems to the the maximum for the type of motor and the type of read write head (i.e. GMR) IBM within the past month or so has developed a new technology, using what they call "pixie dust". Basically they dope the platter with ruthenium. Only about three atoms thick between the magnetic coatings. This addresses the problem of a so-called "superparamagnetic effect," in which data gets lost when the magnetic regions of a disk get too small. With the new design, hard-disk drives will be able to hold up to 100 billion bits of data per square inch. As density goes up, seek times goes down, and transfer speeds should go up.
I think he ment a solid state device. Currently you can buy such devices. if your willing to pay 30 thousand for a 2 gig drive. It's fast as hell and quiet as hell but is it worth that much?
