Pfsense 2.4.2

[ghkrauss]

Gentlemen:

Does Pfsense 2.4.2 have "TRIM" tuned on by default when installing the image?

[kejianshi]

I still remember when I bought a batch of several MCCOE64G5MPP-0VA

Bought them for about $60 each…

SLC SSD SATA 3.0Gbps 2.5"

SLC drives are just indestructible.  All are still going strong.

Anyway - To check to see if it is enabled by default after install, in Diagnostics > Command Prompt try something like:

camcontrol identify /dev/ada0

Look down and find Data Set Management (DSM/TRIM) - See if it says yes and yes.

If so, its on by default if the drive supports trim.  Mine doesn't.  But I suspect the drive will be running strong long after the sata interface is as legacy as usb 1.0

It should be on by default but you can check yourself after installation.

Depending on the filesystem used:

UFS - run this on the command prompt:

tunefs -p /dev/ufsid/

Where <identifier>is the UFSID for the root filesystem, you can get that from /etc/fstab from the line that has "/" as the mountpoint (second column).

ZFS - run this:

sysctl vfs.zfs.trim.enabled

If it reports value of 1 then your system is using TRIM.</identifier>
