Question Seagate Backup Plus HUB 6TB or WD 5TB My Passport Portable

I normally see lower prices on 2,3, or 4 TB external units, perhaps low enough to fund getting a pair of them vice just a single 5 TB unit in size.... (too many folks relying on external drives for recovery then have them fail when they are truly needed, so, when possible, back up your truly needed files/docs to cloud storage as well)

Nothing against Seagate, but, I'd prob go with WD brand if forced to choose...
