Ok, so I emailed sandisk asking if this SSD is 24nm NAND, 34nm NAND, etc.

this is their response:

"As per you query SanDisk Extreme uses 24 nm Toggle Mode flash. Today we are the first SSD manufacturer who has combined the good old SandForce SF-2281 controller with new 24 nm Toggle Mode flash. We have recently released the SanDisk Extreme II SSD which uses 19 nm Toggle Mode Flash."


hmm, the new Extreme II is 19nm NAND,?
i would think this would last even less than the Extreme @ 24nm
