Performance wise it very good.while using it in 2.0 port the copying speed is nearly 25-30mbps and writing speed is about 10-20 mbps.But in 3.0 port the speed is awesome , reading speed is around 60-70mbps and writing speed is 25-30 mbps.It comes with some useful software like password protecting your drive , 1tb cloud storage, backup and many more.
I am personally using it and till now no issue has come. It is quit handy., lighter and perfectly fits in your pocket.The service is also very nice from the wd service provider as my friend had some issue with the product so they directly replaced the item.It also comes with 3 yrs warranty which is preety good.The price is also good and cheap compared to other famous brand.So I will suggest go for it.
