I just received my new 2019 iMac and I haven't even been able to use it yet because it's taking FOREVER to restore my Time Machine backup from my old external WD drive (it's not USB 3.0). I am now looking for a large, external drive I can use with Time Machine. I was looking at the WD Passport Ultra drives but read they don't play nice with Time Machine. I need something like a 2TB drive. Any recommendations??? I've ordered a Samsung X5 for external data storage, but I don't want to spend that kind of money on a drive solely for Time Machine. Any help would be appreciated!
