I’m using "WD My Passport Ulta 1TB" from 1 year.It is a very good storage device.I place my all music, videos, song, movie, pictures on it.
It is very light and very portable.
It can give read speed approx 80-90 Mbps and write speed of 85-90 MBps. Customer service I love it. They had a very good customer service. If your hard disk doesn’t work properly they will change it qucikly. I changed my hard disk 1 time because I dropped off many times and 2-time cable of it.
I think WD doesn’t do is making an image backup of your all content it. You will also get 3 years warranty from the company.
