I can sell them to you for cheaper than that. If you look at my asset comparison I sell them in my asset for $36/TB and you dont have to worry about electricity, plotting, drive failure or anything.

So if you want to buy them I would do them for $125 plus shipping. I am in Canada though so depending on your location shipping could kill the deal. No minimum order quantity either, but I think you would save on shipping the more you wanted. They would all be either 4, 6 or 8TB drives. Nothing smaller.
