Large flash chips are obtainable?

Bud:
It is all can be done until time comes to sell it. How you are going to advertise, sell, ship, support, handle returns, etc. Is it going to be out of your garage? Even Apple had to provide customer support to the (only) 200 customers who bought their Apple 1 gizmo.

coppice:
It shouldn't be hard to get 16GB QSPI chips in modest quantities. They get embedded in many things, so there is a market for them in both small and large quantities. Those aren't the kind of chips that get used in SSDs, though. Chips that will support the kind of high performance people look for in an SSD are only sold in large volumes with direct vendor support, and directly interface to an SSD controller chip. This is because the only market for them is the various forms of SSD, and those are only made in high volumes.

CChin254:
Some small SSDs use 16 GB NAND Flash, such as the OCZ RevoDrive 350 SSD 480 GB. That SSD uses 32 16GB NAND Flash chips (Toshiba #TH58TEG7DDJBA4C).

CChin254:
You could by large (128GB+) NAND Flash chips made by Micron, but the datasheets are not publicly available. You would probably have to contact the manufacturer for them which then comes probably under a NDA and if you plan buy a lot.

My Idea needs a serial Flash chip ^-^ the problem is that I could not find large ones, even with Big prices to pay.

Do you have part numbers?
