#SSD total nand writes 8x higher than total host writes- is this normal?

according to CrystalDiskInfo, the Total NAND Writes (71.1 TB) are 8x higher than the Total Host Writes (8.8 TB). the SMART health is listed as "Good". is this normal, or is it an indicator that something is wrong?

for context, its an old laptop that initially refused to boot. drive repair failed, so i reinstalled windows on the HDD (couldnt install on SSD)

#

after booting into the OS, the SSD showed up, but attempting to access any folder took ~10 minutes, and after 3-4 tries, it would fail with A device which does not exist was specified.

#

deleted all of its partitions with diskpart and created a single fresh partition, and now the drive seems to be ok

#

i dont know what caused the failure in the first place, so i want to know if it looks like its going bad to determine whether or not to replace it

just install hw info and go to the drive section

#

enable sensors

#

find this

#

and see the drive health

#

mines at 22tb writes and 123 tb reads so that looks about right

#

im sure your drive is fine

thanks for taking a look- just to check, those numbers i posted werent reads vs writes, they were nand writes vs host writes

#

nand reads are just the total actioning of the nands
not the actual reads and writes

#

install hw info and get more detailed info

#

this would help you not be so worried, and you have control to see over multiple sensors

ok, this is what i see there, which is roughly the same thing that i see through crystaldiskinfo

this was for a sandisk
i think nand writes are supposed to be high
