Season's greetings, Neale! You've got a solid setup with the DS920+ and your storage configuration. Now, regarding your expansion plans, Synology Hybrid RAID (SHR) is indeed flexible. If you add a 20TB drive to your current mix, it will be utilized at the 8TB capacity of the other drives. However, the good news is, when you later replace one of the 8TB drives with another 20TB drive, you can then expand the volume to utilize the full 20TB. SHR allows for this dynamic expansion and flexibility in managing your storage over time. So, yes, your idea of starting with the 20TB, swapping an 8TB with another 20TB, and expanding the volume to reach 32TB is feasible. It's a smart move to leverage your external SSDs to manage data during this process. If you have any more questions or need further guidance, feel free to reach out. Cheers!
