Works fine, good price/GB

Storage Size: 2TB

I bought this to back up my macbook using time machine. It's working fine for that purpose - just a good basic drive, doesn't take up much space on the desk, and didn't cost much. Nothing to complain about.

Well priced product!

Storage Size: 4TB

We needed extra storage for a project and thought the 4TB would be a much higher price - previously purchased a 2tb harddrive and
thought that was a resonable deal! Plenty of space for our requirements.

Thank you - great service too!
