Proliant 380gen9 & P440ar & Mixing 12g SAS & 6G sas

This seems like a basic question but I have to ask...

 

With the DL380 gen 9 and P4540 controller, can I mix 6gb SAS and 12GB sas in the same RAID 6 array?  I assume the 12GB sas drive would know to slow down but I have read some places that some controllers may have issues with this and won't slow down the faster drives to accomodate this.  Is there any official documentation from HP that would state this?  I’m looking to expand my storage on my g9 and it currently ahs 1.2TB 6g SAS drives -  718292-001 with 12GB sas drives - 872479-B21.

Yes you can mix,  all the drives in the array would then run at the slower speed.
