My 512GB SSD is showing 0% health in both CrystalDiskInfo and Hard Disk Sentinel after recording about 66TB written. I was told that a 512GB SSD should typically last around 150–200TBW or more. Is this health reading normal, or does it mean the drive may be defective? I don't know whether the endurance rating depends on the specific brand and model.

The expected lifespan depends heavily on the exact model, not just the capacity. Check the manufacturer’s specification sheet for the drive’s rated TBW. Some budget 512GB drives may be rated near 100TBW, while better models can be rated several hundred TBW. Also check temperatures, since excessive heat can damage or disable the controller.
The 150–200TBW figure isn’t a universal rule. Find the exact model number and compare its official endurance rating with the SMART data. If the drive is still under warranty, save the diagnostic screenshots and consider replacing it, particularly if you’re seeing errors, freezes, or corrupted files.
That isn’t generally normal, but it can happen. SSD health estimates are based on the drive’s own SMART data and endurance rating, and a failure in the flash memory or controller can cause the health percentage to drop unexpectedly. Back up anything important before doing more testing.
SSD quality varies a lot between brands and models, especially among very inexpensive drives. The capacity alone doesn’t guarantee a 150–200TBW rating.
