A faster hard disk will not run any cleaner than a slower hard disk.
What messes up the file structure is the operating system, and software installation and removal.
I have my 60GB hard drive split up into 7 drives.
The operating system and some programs are on C:
Applications are installed on drive D:
Drive E: contains back up driver and OS files aliong with the paging file.
Drive F: contains a our user files.
Drive G: is where we install games.
Drive H: holds our digital images.Drive I: is where I store downloaded files and web pages.
I can back up selected content with ease.
I can virus scan downloaded files by scanning only 1 drive.
I got started with multiple partitions when I upgraded to a large drive under W95 and FAT16.
Another advantage of multiple partitions is reduced drive space waste.
The smallest file will take up a full cluster on any drive. If your cluster size is 32K, then each file uses a minimum of 32K of drive capacity.
It doesn't take a lot of 1K files to waste 1MB of drive space.
