The lifespan of a hard drive that has been powered on for over 40,000 hours may be shorter, but it does not necessarily mean that it will fail soon. Hitachi Enterprise drives are relatively durable, so they can continue to work for some time under normal conditions. However, it is recommended that you back up important data in a timely manner and monitor the health status of the hard drive. If any abnormalities occur, please replace it promptly.
