WD My Book Studio II compatible with WD 1 TB My Passport?

Hi Guys

Might be a strange question, but since my WD My Book studio II needs a buddy where I can store my files like a copy (just copy the folders on my WD My Book Studio II Edition and paste them on the portable one), I was wondering if the WD 1 TB My Passport is a good solution to buy, or are there better solutions for a WD Portable Drive?

Best regards

Bob

Sounds like the best option for me

Can I connect the My Passport Studio (firewire 800) with the My Book Studio without going via my MacBook?

Thanks!
