This is up to china.That's awesome.....my hope is we start to see some ready to go kits that have the new Nand chip already mounted on a board with the quick connector, and then we will start to see it gain traction as it will be easy as pie to upgrade.
I did mine to a local smd repair shop be fore months. But if I can get a 256GB samsung already mounted on the custom pcb, it would be the best.
