I have used many external harddisk of various companies but no one is like this and we all also know about transcend which is good company.
Now I am directly going to talk about their features it is laced with some good extra technology which makes it different from others, its speed is amazing with USB 3.0 makes it amny times faster than its lower value.
Generally 2TB is enough for storing all required data safely, as it is safer from others because it is shock proof which is very necessary for all important harddisk generally all are important.
It is available in market and also online in reasonable price with combination of good colours, so if you have to take then I will highly recommend for it by seeing all features and price, as its price is average among all.
