SanDisk vows: We'll have a 16TB SSD WHOPPER by 2016


Data retention

Ok fair enough - you write once therefore the cells don't wear out. Wear levelling and garbage collection are not needed, but what about the data retention on TLC cells. I've seen figures banded about that 34nm MLC is good for 5 years unpowered (that is without garbage collection moving the data around) - hardly archive suitable really. Makes me wonder how long the data will last on TLC at even smaller processes.
