It worked 'ok' for two to three years. Over the past six months I've had stuttering issues in some games, ruled everything else out as most of my hardware was upgraded and all the other stuff was relatively new. Completely died on me a couple of weeks back. Tried recovering data and the drive itself but to no avail. Over the years I've found Scamdisk to be the worst brand of hard drives and memory sticks. They are a brand of Western Digital (from which I've also had numerous drives fail) so that says it all really. I have Samsung and Kingston SSDs and an old Hitachi 1TB HDD for much longer than this drive and they're all holding up to this day.

Very good
