Ignore the part about where the partition is, then.
1. If I look at 2TB vs. 8TB HGST drives, their seek times are 8ms and 9ms respectively. But if you're only using a quarter of the 8TB drive, the drive arm needs to move less than a quarter as much. Won't that save at least 1ms?
2. The 8TB drive has a lot more data per inch, and it's spinning at the same speed. Once a read or write begins, it's going to finish a lot faster.

3. Here's a benchmark putting 8TB ahead in every single way http://hdd.userbenchmark.com/Compare/HGST-Ultrastar-He8-Heli...
