So, I have Crucial MX500 SSD, and on their spec sheet, the SSD Endurance TBW is 180TB

Crystal Disk Info says the health is at 33% Health, despite Total Host Writes being 54039 GB (30% of specified SSD endurance TBW of 180TB)


So is their specified endurance wrong, is the Total Host Writes data in Crystal Disk Info misleading or wrong, or is there more things that go into determining the “health” of an SSD besides Total Bytes Written? Or could it be that I mistreated the SSD causing its health to get worse?

    Write endurance is based on the entire drive. If you had the drive mostly full, fully formatted with no overprovisioning, and kept using a small portion of the drive, it matches your expected lifespan. You maybe did a little better than expected.

      Yeah, thats pretty much how I used it, it’s almost always almost full haha.
      So what are some things you can do to make sure your SSD lasts longer?

        You can leave 10% of the drive unformatted. A good drive will move rarely written cells data to high use locations. You could also reformat every couple years and instal based on the least changing stuff first. Next time you buy an ssd stay away from qlc or plc as they have less lifetime. Tlc is about as good as you can get now.

        For now, I would retire that drive and use it for games you don’t uninstall.
