At one company I worked for we divided the disk into 4 quarters and
used only outside two or one for most demanding databases. In extream
cases we could go as low as 12 or less percent of disk surface.
> > The 75% full thing is discussed by James Morle the last database forum. The 75% figure and potential performance drops have to do with read speed which is higher on the outer edge of a disk because of higher sector density (and lower seek time of the read/write head because movement is reduced).
