New Backup Drive Recommendations

My MyCloud NAS drive dies after one year of faithful service (sheesh) and I am now in the market for a backup device. I haven’t bought one in years so I’m a bit out of touch.

IS NAS the way to go, or could/should I get a cheap spinning USB drive to hang off of my ROCK? The only disadvantage of a USB drive is its proximity to the primary drive and all of its risk exposure. I do back up also to the internet so I’m pretty well covered I suppose.

I’ll want to match the size of my library drive (4TB). Any manufacturers to avoid? favor?
