Firstly, Hello, as this is my first post I have a MBP and the wife uses a Windows laptop. I have decided to purchase a storage/backup solution and having taken to the Drobo. But as im a novice in this area im getting slightly overwhelmed by the choice thats on the market along with all the tech talk that accompanies this kind of hardware. I like the Drobo based on the simple user interface and also the ability to change the drives once full or should one fail. The prices here in the UK seem reasonable as its being bundled with the Droboshare which also seems attractive as I would then be able to share files with the wife's window laptop and will make photo sharing alot easier than constantly copying fils to a disk etc to transfer. I was just about to order the other day when I noticed the Western Digital My Book World Edition II 4TB. This also seems to fit the bill at a lower cost and is also PC/MAC compatible. Can anyone offer any feedback on either of these systems. I know cheaper systems can be built by more knowledgeable individuals but im completely out of my depth doing anything like that. Thanks in advance.
