The new storage blade has only been upgraded to the P410i controller,
and even though there is a new setting called "elevatorsort", which is
enabled, the performance is just as bad. The new one has a
flash-writeback cache and may be faster by a few percent ticks, but
that's it. It doesn't even make sense to compare the two in-depth, as
they perform almost identically.
