Mike, that was true at one time, today using bit density, the sectors are relatively close in size, regardless of physical location on the platter. Spin speed is still a limiting factor, but catalog lookup for the data location and defraged sectors are the biggest factors in response.Bartonmd said:And actually, I'm not a computer hardware guy, but am also a sparky by degree. It's my understanding that hard drives have the more full = more slow issue only because they spin at a set rate, and start recording at the outer part of the platter, which has the highest transfer rates. As you go inward, the drive is still spinning the same speed, but there are fewer bits per revolution. Not only that, but the heads have to move back and forth farther to read the information, as it's more spread out.Mike
Still has the catalog and defrag problems. Speed is now a factor of clock speed.Bartonmd said:As far as I know, silicon recording media does not have this effect, as there are no mechanical parts involved in accessing data. There is a data rate that the memory chips can through-put, but for a given load, full or empty doesn't really matter to speed.
