Now a days usb drive is very important to us as we store important file in it.for drives only one usb drive is very important and thats enough for us to use . if two usb is present than it is waste of technology and waste of money for us.
I am using it since 4 months. iam still using this only one usb drive and one I am not using . hence this type of technology is waste . only single type of usb drive is enough . as technology goes to forward than speed and working product will be slow. this happens in this drive. if I use in both the usb drives alternatively than it will not work properly . hence this is a waste of money and technology.
