How are planning to back up your data ?

I am planning on buying a HP computer and is given the option of a second hard drive.
I have a lot of pictures and video files and will want to use the computer as a PVR.
Is there a difference with a 2 TB hard drive or two 1 TB hard dive?
The price difference is about $130 more for the second hard drive. Is it worth the money?
Thank you.
