Question about Seagate BarraCuda

In general you can use any hard disk in a NAS, of course the NAS suitable disks are recommended, but if you also use a good backup concept and a RAID 5, then it is less of a problem that they are not NAS disks. The only disks that broke in my case were NAS disks, but it is not a question of whether they will break, but only when. I would, however, take Seagate Barracuda 2 TB if the price is right.

Seagate Barracuda (2 TB, 3.5", CMR)

If you use the disks in the NAS and do not use them 24/7, then yes at best. They are not NAS disks... but if you are "on budget" and will be using a backup, then at best it might work...
