content: As you said cheap "consumer grade drive" these things never come out as cheap. Seagate on Newegg (I'm only using Newegg as the seller, and not discounted prices), 4TB $179, 8TB $399, for desktop drives that is 2x capacity and 2.2x the price. Though that drive pictured is not a desktop drive but an enterprise one according to the sticker I'll check those 4TB $399, 8TB $559, 10TB $599 so 8TB 2x capacity 1.4x price, 10TB 2.5x capacity 1.5x price those actually show some savings though this will have to come out at less then $958 to be cheaper per TB then the 10TB drives.
