Period TRIM: how to enable discard on SATA SSD drives only?

My storage is composed like this:

• 1* Samsung SSD 850 PRO 256GB [SATA] (/dev/sda)

• 1* WDC WDS256G1X0C-00ENX0 [NVMe] (/dev/nvme0n1)

• 4* Rotational mechanical HDDs [SATA]

# lsblk --discard

I was wondering how to enable periodic TRIM only on Samsung SSD 850 PRO 256GB [SATA].

Thanks!

Re: Period TRIM: how to enable discard on SATA SSD drives only?

Follow https://wiki.archlinux.org/index.php/So … iodic_TRIM then edit fstrim.service, something like this in override.conf should do it:

[Unit]
ExecStart=
ExecStart=/usr/bin/fstrim /path/to/Samsung/mountpoint
