Can you explain why 2x-nm Toggle NANDs would drive down the costs? I assume you meant the smaller 2x-nm process (more NANDs per waffers due to smaller size) and not the actual Toggle DDR part, right? From what I’m seeing so far, the current 20nm NANDs are now the same price as what the pervious gen NAND pricepoint was when it was first released last year for the same capacity.
I was wondering when we should expect the next drop in price or more precisely, more storage for the same price and not the speed? It feels like we won’t get any until later next year when they do another nm process improvement.
I hope the companies would focus on giving us more capacity in the next gen instead of more speed. I doubt most customers care about getting 500MBps read/write, especially at whatever is possible in the next gen.
Hope to see 240GB (current gen) for 300$ by the end of the year and 512GB for 400$ by late next year.
2x nm toggle NAND is expected to drive costs down because current toggle NAND is 3x nm.
People would care about getting 500MBps read, as that would be just 62.5 MB/s - dog slow compared to current SSDs and not even on par with sequential 2.5" HDD speeds ;)
And there's not much the controller can do for making SSDs cheaper, except not costing too much itself. The bulk of the cost is the flash, independent of SSD speed and controller. So optimizing speed and cost are almost independent, both are being worked on at the same time.
Regarding cheap 240 and 512 GB SSDs: try to use the smaller capacities in a smarter way..
Actually SSD's far surprass sequential speeds. These sata III drives can theoretically hit 750MB/s read speeds but usually do not go over 550-575.

Mb = megabits MB = megabytes.Actually SSD's far surprass sequential speeds. These sata III drives can theoretically hit 750MB/s read speeds but usually do not go over 550-575.

^^^ Very wrong.

So those stupid Macbook will finally have SSD that is half modern.
