You don't have to wait, there is a 1.9TB E12 drive on the market now for around $350 or maybe less by now. Do a search. I'm sure we are about to see in the coming weeks / months possibly larger E12 drives. There are massive profits on these NVMe drives as they use literally $35 dollars in parts and factored into that cost is labor, lights, replacement, etc. I saw the cost of these chips somewhere, they aren't much. General rule of thumb for wholesale, retail pricing is that if they have a $99 shelf price, then they've paid $49 or less wholesale per unit. The factories making these drives profit from quantity. While $15 or $20 profit per drive may not sound like much for the factory, multiply that by 250,000 drives a month. All of a sudden you're talking big numbers. Where do I get my numbers from? I don't. They are just random possible monthly production numbers. But I am fairly certain I'm in the "ballpark" of what kinda profits the manufactures make per unit. I've read these numbers can be anywhere from 8$ to as high as $20 or $25 per unit. The next step in the evolution of all of this is a larger E12 drive. It's not if one is coming, but when. It will probably happen slower than you want but faster than you think.
