Thanks for the advice guys.
I can see this isn't going to be a plug and play type of thing.
I'll have to try to learn what I'm doing, before I actually do anything.
Raid 6 would still give me 64tb of storage, that should be enough for years to come, so I'll study up on that more.
As for the cashe, I don't see how that is going to help much, this will be for mass storage, not everyday access.
Maybe I'm wrong ... more studying.
Anyway, thanks for the info and direction of things to look into.
I have many NAS (QNAP and Synology) including four that have 10Gb ports (typically SPF+, but 10GbE would be correct for the MACs). The closest one I have to the DS1621+ is an 8-bay QNAP with the same CPU and 18TB drives. I tend to prefer RAID-Z2 (RAID 6) for 8 bays and RAID-Z1 (RAID 5) for 5 and fewer. On principle I prefer ZFS (QNAP) to Btrfs (Synology), though both are COW and better for data integrity than EXT4, which is the default and certainly fine for many users. The ZFS and Btrfs do exact a performance penalty.
You probably won't see a lot of benefit in SSD caching for large (photo and video) files and small numbers of concurrent users. In some cases the SSD will be bypassed for large files, but check the documentation. That bargain Synology deal has only 4GB of RAM, which impacts performance and in some cases limits volume sizes and other functionality. One of the benefits of the embedded Ryzen CPUs is that they support ECC RAM. I suggest 16GB or the max of 32GB.
