I kind of thought that hard drives used the same storage rules as CD's, where it's beneficial to put files towards the outside for faster reads (unless CDs do the same thing too).
Here's a quote from that site:The stack of platters rotate at a constant speed. The drive head, while positioned close to the center of the disk reads from a surface that is passing by more slowly than the surface at the outer edges of the disk. To compensate for this physical difference, tracks near the outside of the disk are less-densely populated with data than the tracks near the center of the disk. The result of the different data density is that the same amount of data can be read over the same period of time, from any drive head position.
So what it's saying is every track fits the exact same amount of data, and it does not matter if the data is on the very inside track or the very outside track because they will be accessed in the exact same amount of time. On any hard drive, the point where the head is exactly in between those two tracks really is the half-capacity point of the drive, i.e. 30GB point on a 60GB drive. I guess if you take into account the file allocation overhead, etc., then that halfway point would be shifted slightly but not enough to affect our purposes for optimal swap file location.
