A couple years ago the Samsung 850 Pro SSD in my pc died. About two weeks ago I realised it had a 5 year limited warranty. I guess I need to read the instructions, eh? Any way, I contacted Samsung and they told me to contact their support service. I did and the told me to send it to them, on THEIR ticket. Today I got a replacement 860 EVO SSD. No questions, no fuss, no charge. Talk about standing behind their products! Most US companies would just say tough noogies and make you buy a new piece (hear that HP?). A tip of the hat and a pat on the back to Samsung.
