I am using this hard disk from past 6 months and found it very useful to carry large volumes of data. Following are the features of this hard disk:
It has good storage capacity which is 1 TB.
It is very lite in weight only approximately 180 grams.
It's size dimensions are also very small .
It's transfer rate is very fast.
We can carry it in our pocket because of its size and weight. It is very useful as it is very time efficient because of it's transfer rate.
