I want to buy a backup drive and I wonder whether I should buy a single 16TB or two 8TBs given that the costs are the same ?

Is it a better practice to split the data into half and have them on two 8TBs instead of having everything on a single 16TB ?

What you want is all the data on 2 different devices.
So that if one of the devices quits you still have a copy.

Either.

Again...3-2-1.
(you've read this before)

Design a good backup plan.
Implement it.

And TEST IT! Nothing is worse than :
"I have a backup. My house got flooded, and I have no idea how to recover it!"

I have the data already on other disks....I want to use the 16TB or 2x8TB as backup....should I use a 16TB as backup or 2x8TBs ?
Yup that's what I meant.
When the data on the working disk goes wonky and you reach for your backup and find out it's busted is a bad feeling.

That's why the complete backup is in 2 different places.
You might feel that's overkill.

I'd do 2x8 TB. A 50% failure is better than 100% failure. If I were you I'd keep the drives in two different locations. Put any irreplaceable data on both drives, learned the hard way so don't make the same mistakes as I have.
