So far so good, although it has only been a couple of weeks since I purchased this drive. It is connected as a Time Machine drive to an iMac that gets a TON of usage, hence this drive will need to work reliably for about 50-60 hours per week for the next three years to really prove itself. Alas, the 4TB Seagate Expansion drive that I purchased from JB Hi Fi in late November 2020 failed to last one full year under these conditions, so it will be interesting to see if the Western Digital goes further.
