Interested to hear any opinions or feedback on the My Cloud 4tb.

I get a bit confused with the WD range, My Book My Cloud Passbook etc?

Basically I just want to upgrade more storage capacity, I don't think I need the cloud option really.

I've got a reasonably large iTunes library and also a fair iPhoto library, at the moment i'm using around 1.5tb of storage.
So I'm thinking of going to a 4tb drive.

Right now JB are offering the My Cloud 4tb at $279, seems like a good deal, but they also have the 4tb My Passbook for $199.

What about Synology or others, prefer to ignore Seagate as I've a 2 failures with them.

Any help is appreciated.
