However the 1TB drive had a partition of 10/90.
What are you going to do with the 900GB partition?
My "guess" - assumption? - is this is 100/900. And if so, that makes sense to me with the 100Gb as C, the boot drive, and the remainder for data, installed programs, backups, downloads, temp files, and more. I would not move the page file. Keep on C with the OS.
You have restricted the movement of the drive heads to the outermost tracks on the platters where the density of sectors is aprox 3 times greater than the 160GB drive.
I don't believe density is the issue here. Neither is the fact these are "outermost tracks". Though those may be factors, the issue - key
benefit is the fact the drive head is restricted to a small zone on the drive - and that's a good thing! Good because it means if the next file segment is way over on the other side of the partition, it does not have far to go to "seek" it out.
That's a good article over at Symantec but it is huge - talks about a lot of things, primarily hard drives in server/enterprise environments - so not sure the point you are trying to make with it.
I note for "normal users" - not server admins - partitions can help us keep our computers organized the way we like, and if setup properly, do not impact performance, but in fact may allow us, the human component, to work faster. Separate drives would be better than partitions, but you go with what you have.
But again, drive performance is but a small, though important component in over all computer performance. The only real way you are going to improve drive performance significantly is by going SSD. Devices that rely on motors and mechanical actuators (even the latest 15,000RPM drives) will always be a limiting "memory" factor in our systems. And unless you use multiple drives in a serious RAID0 striped array through a dedicated (and expensive) hardware RAID controller, "overall" computer performance gains will be minimal - unless you consider a few seconds shorter boot times a priority.
Again, ideally, you should ensure you have enough RAM to load the entire program into RAM. Then who cares about drive performance? This is another area where 64-bit shines.
