The platters in a harddrive are alot like the old Vinyl record albums. When they spin the outter portion is moving under the needle much faster then the inner portion.

With harddrives this causes the inner portion to read and write much slower then the outer portion. I suspect you are writing to a partition that you created on that inner portion so you will never see 100+mb/s there.
