The cheapest Samsung drive on newegg right now at 250GB is 99$. So basically, you want 4-5 times the peak performance at a 40% discount. Must be nice negotiating with you.
I'm happy to see more controllers that support NVMe but the final paragraph kind of took the wind out of my sails. While I obviously want to see cheaper SSDs, I'd hate to see that at the cost of stability and performance. Storing only the mapping tables that can be fit in the controller's SRAM cache seems very limiting. It's not like these are full blown server CPUs with 32MB of cache. Would it not be more reasonable to integrate a smaller DRAM cache in PoP? Perhaps eDRAM has made some strides in recent years? A controller with 64 to 256MB of eDRAM on the same die?
If it was talking about mid/high range parts I'd agree; but that's a race to the bottom design. An area where saving 2 cents is more important than a even a 2x performance penalty; which is why race to the bottom laptops still mostly have HDDs. Even a crappy SSD is faster than an HDD; anything to help transition WorstBuy special laptops to the future is a net win.

honestly i can't get excited for nvme unless we get 240 gb for ~$60 AT LEASTdragantoe - Tuesday, June 9, 2015 - link

I'm not getting excited for hardware at allit is just tools

Why are you here then? This is a PC hardware site.fokka - Tuesday, June 9, 2015 - link
so you want fast as fuck and cheap as fuck. i guess you'll have to wait a little longer.Gigaplex - Tuesday, June 9, 2015 - link
So you'd turn your nose up at 240GB of NVMe SSD at $70? You're hard to please.euler007 - Wednesday, June 10, 2015 - link

I'd be very concerned about the retention of TLC NAND at 16nm.Samsung had trouble with their evo drives using TLC 19nm NAND, I can't imagine how bad it would be at 16nm.

I wonder if not only the bottom end, but also for Mobile SSD will move towards DRAM less controller. Since DRAM will add to power consumption.
