This proves one and only thing yet again :

-do not rely on SF drives and avoid like the plague these doomed controllers
-34nm will always be better than 25nm ( just like 50nm Vertex beat everything so far but probably will be beaten by a capable C300 of same size due to lower WA in the C300; no amount of controller magic will be able to overcome the physical limitations of 25nm NAND )

The industry is trying to fool us with 22nm and even lower. They will soon realise that unless another material is used, things cannot scale below a certain limit without severe consequences. The game is up for the SSD and semiconductor industry. No coincidence the Intel SB-E has so many problems with virtualization and the like.
