Can I use this device to backup both my PC and an external drive connected to my PC via USB (e.g., My Passport)?

I don't see why not. I'm currently doing this with my Mac. I have it set to do a Thursday backup to one folder and use it as an external drive in other folders. The thing I cannot do with this method is to have a bootable backup. With that said, I could partition the drive to make my computer view it as two harddrives. I could then make one of the two bootable. So in answer to your question with the PC. Yes. Of course. Just make a subfolder on the drive and setup your automatic backup settings to store the backup in a folder inside the root of the drive. With that said, this is true with any harddrive, not just the model.

What's the RPM for this harddrive?

On mine: zero. It failed within a year.

Where can I find the link or app to run back up?

My unit crashed...have had problems from day 1, trying to recover data at this very moment.. cable connectivity issues also...
