Inspiron 660 system drive mirroring

[shortmort37]

I have an Inspiron 660, and I'm running Windows 8.1. I'd like to software mirror my 1 TB system drive to another. Is this possible, and how can I do it without trashing my existing system drive? If so, can someone outline the steps for me?

Thanks
Dan
