2.2.4 and how I enabled TRIM

kapara

I wonder if it is a batch of bad Samsung ssd's

I recently built out a new box on supermicro MB. Enabled trim without error. I did have to use 64bit, and installed off of usb 2.0 port and disable AHCI. Legacy IDE only. No issues so far!

" I did have to use 64bit,"

64bit worked here too, but not 32 bit–-

@ThePOO:

–---- I was pretty frustrated getting TRIM enabled in 2.2.4

------ This is what worked for me to get the trim status set to enabled for my SSD.

Thanks for this guide, I just successfully enabled TRIM on the 16GB mSATA SSD module of the apu2c4!

@jimp:

Devices purchased from the pfSense store are loaded with TRIM enabled since we know the hardware and disks are capable (or at least in some cases do not have a negative reaction to it)

This wasn't the case with a new set of HA rack mount SG-4860's just purchased (thread https://forum.pfsense.org/index.php?topic=113803.0). Has this changed? Should the HA set of SG-4860's have TRIM enabled?

Thanks,

I just used this guide to enable TRIM on my new Samsung 850 evo msata drive. Rebooted and everything looks as it should.
Should I be concerned about corruption or would it be immediately obvious if there was a problem, I'm using pfSense x64.
Thanks.

@2chemlud:

This whole TRIM thing is a pile of sh*t on i386 BSD…

TRIM is an ugly hack, period. Mainly a symptom of trying to graft old storage technology that works one way on top of flash memory that works an entirely different way. Hopefully someone will come up with a replacement for SATA and develop a native flash memory stack end to end.

Until then I just buy SSDs that are over-provisioned and do their own garbage collection irrespective of TRIM. Most Sandforce based SSDs work this way - it just takes a bit more digging to find 'em.

It's called NVMe.

With regard to over-provisioned SSD a good article (at least from Kingston) is
