Using a Partition to Speed a HDD?

Okay, I understand that first 1/3 of a HDD is going to be the fastest. I believe this is primarily because the data will be placed in the outer portion of the platters which are "faster" at a given r.p.m.

My question is this: Can I partition a HDD into 1/3 and 2/3 segments and have the 1/3 segment placed on the fastest part of the HDD? The goal would be to use that small (faster?) partition for applications and have the remainder for basic data storage. If this is possible and makes sense, is there a special way I need to create the partition in Win7 to make sure the 1/3 segment is in the fastest portion of the drive?

Finally, would it matter if I were using two HDD in a RAID 0 and wanted to partition the combined drive this way--1/3 and 2/3?

Thanks!

Depending upon platter size, at a fixed rpm a point on the outside edge is traveling at a "linear" speed perhaps twice as fast or more than a point on the inside edge. It is my understanding that this is why the first 1/3 of storage on a HDD is the fastest. Someone please correct me if I am wrong.

Okay, then I guess I don't understand why the first 1/3 of capacity is supposed to be much faster. I realize you can't fill a drive 100%, but surely the temporary file/other overhead processes don't require 2/3 of a HDD. Sorry for the newbie questions, but I guess if I don't ask, I'll never learn. Thanks!
