My Book Live or N900 Central better?


I’m thinking to get a personal cloud storage, facing 2 options:

  1. My Net N900 + My Book Live (2TB), or

  2. My Net N900 Central (2TB)

Which is less costly and more effective?

Basically i dont need any backup feature, my priority is high speed and easy configuration and access.

Please advise, thanks.

The other question i wanna add…

I saw My Net N900 has personal cloud feature.

Can I just get that router plug with My Book Essential or other USB storage to access the personal cloud?
