How to best use my brand new Seagate Backup Plus Hub 8TB and 10TB external HDDs?

Long story short, I have a few of the Seagate Backup Plus Hub 8TB and 10TB external HDDs. They're brand new. I would rather not sell them and lose money. My thinking is to just shuck them and use them in a Ubiquiti UNAS or a UNVR. Might not be the best possible performance, but not the worst either? What do you guys think?
