RNDP6000-200EUS vs RNDP6000-200NAS

Of course you-dah is correct, however Netgear does control product information on their website. The information provided does not list a diskless Pro 6 unit on either the uk nor USA site. Netgear should also be concerned about customer satisfaction. The situation where 1 lesser product costs as much as a better product with longer warranty will lead to unhappy customers like myself, particularily when it was so difficult to be aware of the alternative,better product. The prices for the populated units are disproportionately high (3x1tb unit effectively adds 450 pounds for the disks. It's therefore only on these forums that I discovered the existence of the diskless unit, and too late. I can't return the ultra 6 plus without incurring a 15% restocking fee as I purchased it 4 weeks ago.
The store I'm looking at is Kikatek
