Literally any modern router sold these days have usb support where you can connect an external hard drive to it. So any router really.
Same here! A few years back I put a 2TB 2.5” drive in my 2008 time capsule and it’s been rocking out ever since. The 2.5” drive generates a ton less heat than the old 3.5” drive did.Oh I thought you meant the whole thing was busted. I'd swap the hard drive out with a faster 7200rpm drive if you are tech savvy and can open it up. Or you can do the external USB route.
I got mine back in 2009 and it still works to this day lol.
Since I am not very tech-savvy. I have a question? If I get the external and attach it to the time capsule, can I have my MacBook pro backup to both at that same time? That way I have 2 backups?
How did it go? Hopefully no issues.
