I have already My Book World from last year and it works perfectly with my MacBook Pro.
I decided to upgrade my local NAS and i bought MyNBook Live.
In each drive i have access via SAMBA (smb://MyBookLive/Public) to have full Read &Write Permissions.
My problem now exist on my new My Book Live because it’s very slow (on reading and writing) and i can’t use it for example with Transmission (torrent download). Every time that ad one torrent it stuck… i need to make force quit…
With My Book world i don’t have this problem.
My Book World it seems to be more faster than My Book Live
