The SSD works good and warranty is also valid as checked online from WD website. But I received the package in a NOT so good condition. DTDC is to be blamed for the condition of the package. There was only a single layer of bubblewrap on the SSD and an outer Amazon brown envelope. All the bubbles had been flattened and it was just a plastic layer. It was a SSD and hence survived the journey. Any other electronics would have been dead. That's why I emphasize on better packing of every consignment as most of the courier are shit in some way or the other.
