Creating a swap file or swap partition on the SSD/HDD

Creating a swap file or swap partition on the SSD/HDD

I have Linux Mint 13 LTS which is based on Ubuntu 12.04 LTS.
I installed it on my SSD and will use the HDD for data storage only. When
installing the OS I skipped making a swap file/partition. The machine has
8GB RAM and I wasn't sure whether I need a swap file at all. But after
some reading I understood that the swap file is used in some cases even if
there is free RAM still. So, it seems that I will need it.
Should I create it like a file or like a partition?
Should it be on the SSD or on the HDD?
If I create it on the HDD, could it be a bottleneck for the system because
of the lower read/write speeds compared to the SSD where the OS is
installed?
What is the optimal size for a laptop with 8GB RAM?
