I don't know what product to buy

I have an iMac - about 5 years old, I have an old external WD but my desktop doesn’t recognise it, and I think it’s not getting enough power. I have probably used 250-300GB space on desktop. I am looking for back up so that I can upgrade my OS, it’s just home use, but as important financial info / photos / scans and MS Office apps and tons of music etc.I expect to use something like the passport for Mac, is that the right product? Anything I should look out for?

Hi,

My Passport for Mac is the perfect option as it works straight out of the box with Mac devices. It keep your digital life’s contents secure with My Passport for Mac password protection and built-in 256-bit AES hardware encryption, it has USB 3.2 Gen 1 (Superspeed USB) that is also backward compatible.
