Adding 2 3TB Red drives to ReadyNas Pro

[jerryk1]

I am going to fill the 20 open slots in my NAS pro with 2 - 3 TB Red drives. Anything to watch out for?

I assume insert one at a time is best?

One at a time is best.

There are two expansion limits (16 TiB ceiling, and an 8 TiB growth limit from the volumes initial size). Both of these apply to the volume size (not the raw disk space).
