![]() ![]() Some final notes: Power on time is more important to a fixed HDD because it has moving parts like bearings, a motor, etc. If you have the 960GB model, then that doubles to approximately 292GB every day. That means that you could write roughly 146GB every single day to that drive during the 3-year warranty before you exceed the rated endurance spec. What we know about that model and capacity drive is that it has an endurance rating of 160TB written and a 3-year warranty. Going off on a little bit of a tangent here, but I'll assume that you have the 480GB drive since I don't know for sure which capacity drive you have. Likewise, write less data and that time will be increased. Of course, if you start writing a lot more data to the drive than you have in the past, then that time would be reduced. If you write data at a constant rate, a current health rating of 91% indicates that you go another ten times that long or about 20 years more before the drive reaches its endurance rating. ![]() Let's say that you have had that SSD for 2 years and you still have 91% life remaining. So, let's take some random numbers here as an example for overall health. Its health status should still be shown as 100% because the health status is mainly a measure of how much data has been written to the drive vs the rated endurance. It's powered on for 10,000 hours but you never write to it. Let's take an example: Suppose you install an SSD in your system, but you never use it. That question cannot really be answered simply because the number of hours usage for an SSD is pretty much irrelevant. You asked if the health value is a concern for a 2,199-hour usage. However, I would suspect that the more important, and more accurate number would be the total NAND writes because that comes directly from the SSD controller. ![]() I'm not certain why the total NAND writes would be lower than the host writes, that seems odd to me. SIW2 is correct - the main thing here is the overall health status which shows 91% of life remaining. ![]()
