Discussion I think Crystal Disk Info is inaccurate.

I just checked 2 of my portable SSDs. Both of their TBW is 600. One is WD Blue SSD 3D and another one is Sandisk Ultra SSD 3D. The Crystal Disk Info shows me something very wrong.

As you can see above, WD has written more than Sandisk, but the lifespan still 99% remains whereas Sandisk indicates 98%.
IMO, WD uses a trick to fool Crystal Disk Info, or the app is inaccurate.
What do you think?

CrystalDiskInfo is reporting what the drive is reporting. Can you show us the report from WD's Dashboard?

Lifespan/health is an arbitrary function, specially for SSDs, based on TBW estimate and usage as well warranty and time to it's end, It's up to program's developer to interpret it. Disks can go bad and/or die even when 101% healthy. There's no program or anybody that can predict that. As long as SMART table is normal, you can be reasonably sure it will last long time.
