Firstly board members - I don't know where this post should go so I settled for here since I have a MBP I'm thinking getting a NAS drive and streaming to my MBP and other devices using Powerline Networking. This technology seems to good to be true. The NAS I'm thinking of is a Synology unit called DS413j url : http://www.synology.com/products/product.php?product_name=DS413j&lang=enu I'm wondering if I put 4 x 2TB drives in this whether I'd be able to Raid 1 (?) it so 2 of the drives can be for DATA and the other two for BACKUP. Does this product seem that it can be used this way? There are many brands of Powerline Networking products it seems and I'm thinking of using a NetGear model. url : http://www.pcworld.idg.com.au/review/networking_wireless_voip/netgear/powerline_av_200/345157 Any help and opinions re this desired system is greatly appreciated. Thanks board members.
