Neat and sleek design.Portability is off the charts.When it comes to data transfer speed, read and write speed both are pretty decent.I am using it as my no.1 data storage these days.I was using seagate but since I bought this, I am loving it.Though I experienced little problem, the customer care was kind enough to get me a replacement.If you need an external storage with blazing speed and performance, dont think twice.Just go for it.
