[SOLVED] Does my WD10SPZX HDD support trim?

[paijoh]

Recently I find my laptop boot poorly, it's using KDE Neon as its OS. From boot log, I found out that there was a service called fstrim that took 12 minutes (yes, 12 minutes) to finish xloading. fstrim is a service to trim SSD, which is weird because my laptop using HDD not SSD. And I decide to stop the service. But when I tried to get the info of my HDD (a 1TB WD10SPZX), I read this two sentences:

* Data Set Management TRIM supported (limit 10 blocks)
* Deterministic read data after TRIM

My question is: does my HDD really support TRIM?

Yeah you shouldn't be bothered with that feature as it's best used for SSD's.

WD's SMR external HDDs support TRIM. Perhaps some internal HDDs do, too?

SMR drives would benefit from TRIM. This is because the drive normally has to rewrite the adjacent "shingles" in addition to the desired data. By enabling TRIM, the OS can tell the drive that it does not need to preserve the data in the shingles.
