But kt is the fastest harddisk ever. It is great choice in transffering data or to move with us. In inda 500 gb is available above 10000 rupees. It has great look. It is very small harddisk or one can say a pocket harddisk or ssd. It can be connected with everyone. It is made of metal no break. It is dam fast about 400 mb per second. It is fully secured. Fully backup system. No idea to lost all data. So if you want a good then buy this only or can say only go for it.Thank you.Have a good day.
