    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.
