Looks like our NAND-based storage solutions are going to get a lot bigger in the near future.

Awesome.

Well you need 8, 128Gb chips to equal 128GB of storage. Which means you would need 64 chips to create a 1TB SSD. So they must stack these.

Am I correct? Or am I looking at it wrong?

Each NAND package typically contains several stacked NAND Flash dies.

The Samsung 840 500 GB for example is made of 8 packages of 8x64Gbit NAND flash dies. A 1 TB Samsung 840 would be probably made of 8 packages of 8x128Gbit dies.

By the way, "3-bit MLC NAND" is a fancy way to say "TLC NAND memory". This news is about more dense TLC NAND, not the 2-bit MLC memory that most people commonly refer to.

This should help keep up with the larger, cheaper SSD trend and that is great news for the consumer. Three years ago I was happy to get a 120GB SSD for $250. Now a 500GB drive can be found for close to the same price. That's a pretty amazing gain in just 3 years.
