The article on why thunderbolt won't come to iPhone/iPad piqued my curiosity.
How much does say at 16GB NAND chip that runs at 20MBps cost compared to a 16GB NAND chip that runs at say 125MBps or whatever the speeds are in the Vertex, M4 type drives?
If Apple iPhone and iPad NAND is maxing out at 20 MBps, then USB 2 should be able to easily support a doubling of speed even when you account for a 25% overhead. So to really warrant a new bus such as USB3, we'd need to at least 600 mbps or ~75MBps before it was really worth it.
What is the top speed for a single NAND chip these days? I assume SSD drives get higher throughput by using several chips in parallel (500MBps=4x125MBps or 8x64MBps).
