I wanted to get people's opinion on whether to get a 3tb Seagate expansion external or the 3tb Seagate backup plus external? I plan on using it as a backup to my computer storage. It will be a cloned drive for my ssd and internal hdd. Then taken offsite only to be back up to every month or so. I know there is a slight price difference for the backup plus and it has a 3yr warranty versus 2yr. What do yall think?
