When performing a clean install, Microsoft recommends that NTFS be used
and that the system be installed in a single partition on each disk. Under Windows XP,
big partitions are better managed than in previous versions of Windows.
Forcing installed software into several partitions on the disk necessitates longer seeks
when running the system and software."

<snip #2>
Microsoft implemented certain disk-layout optimizations in Windows XP.
To perform this optimization, during idle time Windows XP moves pages
used for booting the system and launching frequently used applications to
ensure these files are laid out contiguously on the hard disk. The contiguous
disk layout of these pages results in reduced disk seeks and improved disk I/O,
contributing to improved boot time and application launch time.
Windows XP does not perform these optimizations across volumes. Therefore,
for this optimization to be available to users, the hard disk must be partitioned
as a single volume.
