Any way to TRIM SSD when bios has no AHCI mode
-
one of my full install boxes had a broken HDD so replaced it with an SSD, now the problem is the motherboard doesnt have AHCI mode in the bios so not able to enable TRIM in pfsense, is there any way to TRIM it manually using cron jobs or something like that?
i tried setting the ahci load in loader.conf and alos trim set but that doesnt seem to work

TRIM support can´t be enabled on 32Bit pfSense OS!! And if there is a SSD that supports TRIM
on a 64Bit pfSense OS it can be done with ease, likes shown under the link in the next line.
How to enable TRIM support in pfSense -
isnt there a manual way even to send trim command using fstrim etc which i could install and run regularly?

Sorry, this was in earlier time or in earlier versions of pfSense perhaps like you might do it, but as I am
informed since version 2.2.x it is only able to realize it if pfSense is booted to or in the so called
single-user mode. Here is a statement from @jimp about that, from the same thread, Link -
im on 2.3 32bit so can i still boot to single user mode and get it to work.
if not automatic then by manual i mean every month or so i run some command that would send the TRIM command to the SSD, is this possible?

This is interesting because many other customers and users were reporting that they get
it only to work if they use the 64Bit version of pfSense, congratulation.if not automatic then by manual i mean every month or so i run some command that would send the TRIM command to the SSD, is this possible?
No, it is more like the DMA mode for HDDs, you activate it once and it is running then for ever.
It could only activated as I am informed in the so called single user mode and then it must be switched
again to the normal mode installation. -
@BlueKobold:

Why? There was no problem enabling TRIM on a Lanner FW-7530 running 32Bit pfSense.

Some users or customers where reporting here in the forum that they were not being able to activate the
TRIM support on a 32Bit pfSense, but until they where changing to a 64Bit pfSense system they were able
to solve this by activating then the TRIM support without any kind of failure or getting problems as before.
The SSD they were talking about was the Samsung850 EVO. And so I was thinking it could be the same
issue like they where in. And vice versa, also their solution could be working well here and solve it out. -
possible workaround:
overprovisioning (saferase, then only use <=80% of the ssd at install time)
