Windows 7: Cipher or Format console program to wipe (write 0) across a hard drive

How good of a job does Windows 7 cipher do in wiping a hard drives contents?

I have cmd elevated with administrator privileges and I'm running cipher with /w on a designated 1TB Seagate hard drive. Currently I formatted the hard drive to NTFS with a single partition and volume.

I've seen a hand full of applications that you can buy that will securely wipe the data of a drive so that software data recovery programs can not retrieve any of the old existing data. Instead of spending $30 - 100 for some 3rd party program I was wondering if cipher will do the job that I'm after. I'm planning on using this drive to install Windows 10.

If this is a time consuming process, what would be a good free application to wipe a hard drive?

Or would windows format option be better? For Example:

c:\format f: /fs:NTFS /p:1
