Dan is correct. Multiple platter HDs' use segments of all disks for each partition simultaneously so the HD does'nt have to jump around to find files, and the dick readers run in parallel so to put mord data into the motherboard at one time. The main reason I mentioned using multiple partitions is not as much for mechanical failure, but also if the partition accidentally gets erased or moved by someone else, then you do'nt have to restore all of the files.
Another idea I have is to install 2 HDs' in your computer if possible and designate one strictly for Virtual Memeory (I have only tried this on a PC. I'm not sure if Mac even still uses V.M..) and storage for non interactive files like photos', or media files', or pdf for example with multiple partitions if you want. Then designate the other H.D. for the OS and interactive programs. This is to allow the Virtual Memory and the OS to work simultaniously without making one HD jump all over the place. It improves performance immensely.
