Smart array p431 vs p822

I need to build a new storage system.

It will be based on Dl380p / Dl360p G8

I need to choose a smart array controller, actually hesitating between p822 and p431

p822 has internal connecteur that could be usefull for me. and smart cache standard

p431 is more recent and capable of write-back when smart cache enabled

My issue is that I can't find anywhere what are the perf of both (max iops....). I was able to find it for p420 (i guess p822 will be close to that) but nothing for P822

Globally, is there a doc that compile perfs and difference of different smart array controller?

 

Thanks
