I am using this one. Even got a „clone“ button to copy the contents of one drive to the second without need for any computer. Works great.

While my RAID array is rebuilding, I'd like to return to an earlier question: whether a HDD set can be moved from one Synology device to another, and how.

Soon, I'll have four new IronWolf Pro HDDs in my DS414. But what if the DS414 itself fails next week? Would it be possible to move the whole disk set into a new model and call it good, or should I move them, set up a new array, and restore from backups? It would be far easier to do the former, yet my impression is, it might not be a good idea. Comments?

The only safe way is to wipe the disks and restore from a backup. Using the current disks might work if the new NAS is also a DS414 (or possibly a different model with the same processor type) that was running exactly the same version of DSM before its disks were removed.

Synology describe how this may be done here:

I agree with Simon that this risky.

The way forward with my NAS will be driven by storage capacity and processing power (given that I have same-size replacement hard drives to cope with drive failure) as my music library and family video & photo archives continue to grow. If (when) I get a new NAS I'll buy one with a more powerful cpu (e.g, to allow HD video streaming) and new, larger-capacity hard drives. I have considered getting 8TB drives to replace each of my current 4TB drives as they fail, but this would not address the cpu issue.

Thanks for this. It seems I was being slightly over-cautious as Synology allows HDDs to be moved (subject to various conditions) if the new NAS has been installed with the same or a later version of DSM.

Thank you, David. I've kept a bookmark to that useful article.
