The Hard disk is pretty amazing. It is lightweight and with 3.0 usb it goes upto 120MB/s. Avg speed for writing is 80-90MB/s as on 4GB ram and intel i3 3rd gen processor. Read speed is 150-160MB/s. It is silent and does not get overheated though it get upto 45-50°C when constant writing process is done. But its is normal for a Seagate HDD.
