2142 is not this update...2142 will becoming to OCZ drives probably as FW1.7 soon.

Arowana is a totally different build, it is nand specific and i will say 50nm sammy is NOT supported, so all you guys who flashed to Turbo you have all we can give you.

This release will not please everyone I am sure, we are doing what we can to speed up all the drives with all the nand BUT there are limits as to what can be done set by the nand.
