What is the best External hard drive for Sonoma 14.1.2

I need to do a Time machine back

up for my IMac desktop and a Macbook Pro.

I have two users with different back up files. Is a 5TB

external hard drive enough storage and what is the best brand to be compatible?

I would advise against old USB 2.0 drives for performance. ;)


More seriously, any brand will work. Seagate, Toshiba, etc. Just avoid models with fancy zizmos like finger print authenticators and ignore any special software the manufacturer tries to suggest. You'll be reformatting the drive anyway and letting MacOS TimeMachine software handle the backup process.


A good rule of thumb is at least 2x the size of the drive being backed up (or at least 3x the size of the data if the drive is or is likely to become mostly full). 5TB should be good enough to backup a 2TB drive. If you are backing up 1TB or less I'd even call it overkill.
