If growing capacity on an AFF system, mixing internal and external SSDs in the same aggregate is supported In ONTAP, NVMe SSD and SAS SSD drives are both in the "solid-state" disk class - latency in this disk class is roughly equivalent ONTAP also allows mixing SAS SSDs and NVMe SSDs in the same RAID group
