I love this thing the write speeds are among the top 3 of any gen 3 NvME and its half the price of the other two nearly you can often pick them up for about 79USD. It's been extremely reliable as my OS drive for nearly 10 months now but the write speed is kinda wasted on OS. Probably going to switch it with my 250gb rocket someday soon and the silicon power A80 for CAD files.
