Aaron,
It's the same consideration I will take, If mix them, I will worry about
the jitter of perf.
Best regards,
Norman

overall performance of the pool will be affected by the slower devices. This is the same
reason as you will not mix SSD and HDD OSD in a pool. If the performance difference
between OSD is small, it will be OK to mix. It is also the same recommendation if you mix
different performances of any x86 servers.
