Looking to Purchase the 3TB Mybook

Looking to purchase the 3TB My book for my 2 networked WD TV Live Plus players I have in my home.

How is this drive in simultaneously access the drive from 2 WD TV Live plus players at the same time.  Any experiences from the community would be greatly appreciated.

I would not be accessing the same file.  Also the network is a gigabit network. 

You’d probably get more help posting in WD Live section.
