You don't need a new feature for doing that; just make the partition
on your data drive half the size of the drive, and place it at the
beginning.

You could create a second partition on the inner half of the disk for
archive storage or something similar, if you weren't going to hit it
very often.

BTW, if you want to test random seek performance of various
areas of your disk, you can use my randread program
(http://randread.sourceforge.net) on a raw partition or whole-disk
device, and constrain the block range to the appropriate part of your
device.
