I bought it when I was in class 12 and as my friend suggest I am very rough user. I bought is and I was only 1 among my friends who bought toshiba even I have never used toshiba before so I came home attached it to my laptop and is started, wight light started blinking and copy speed was around 40 mbps, after few months my laptop got fried dew to over heat and after that it stayed unused for 4 months after that I bought a desktop which also has 3.0 usb port I connected it and the light changed to blue light transfer speed doubled and since then I am using it it has been 5 years and it is still lasting, most amazingly lasting in my hand.
so as a product I rate it A+
