The performance is good it comes with a usb 3.0 data cable and that helps in fast data tranfer .it have a good feature no external power supply is needed .and software installation is not required .it works on windows mac and linux . I love this because of the compact.and the service is good they replace if the harddisk fails within 10 days span . and it is value for the money the staff assistance is good . we can cheak online with the details of the hardidisk back and cover the warrenty at any part of time
