Hi all,
The following is what i have read in a magazine named "linux for
you" , To what extent this is true ?
The general rule is that you should always create the locations that
need frequent I/O -/home, swap on the outer tracks , the easiest way
to achieve this is to create these partitions first when partitioning
your hard disk ?
Reason all modern H.D.D's use a concept called ZCAV(zonal constant
angular velocity). this takes advantage of the fact that more linear
space is available on the outer tracks of the disk platter rather than
on the inside tracks. now since the disk spins at a constant rate ,
which is also known as CAV (constant angular velocity) the read/write
I/O speed will be greater at the outer tracks as compared to the inner
tracks
