Was gifted to me by my Sister from Canada.
Product I am having is "WD My Passport" 1TB(931GB usable) black colour one and the design is good and Handy and not that big.
Having been using this from 3 years for offline backup of my photos, videos, important Documents etc.
Size is approximately 11cmx8cmx1.3cm and the wire length is 40-50 cm.
One of the good features I found is that They offer free software for controlling the HDD like Password encryption, error checking and formatting.
The speed are also fast, the fastest I experienced while transferring from HDD to My Passport HDD(and vice versa)is 70-80MBPS
While on the other hand from My Passport HDD to Solid State Drive(SSD) and vice versa is 100-110 MBPS.
Note:Dont confuse between bit and byte, the above mentioned is Bytes
I have used it even in TV, Mobile via OTG but it doesn’t recognise in our MapMyIndia device in the car.
Best part is that I did not have to install any drivers to use it.
