9.1 is a bit old, 9.2-BETA1 or 9/stable will be able to tell you if
indeed your SSD is reporting TRIM via:
camcontrol identify <disk>

Subject: TRIM or no TRIM?
Hi,
I've got a 9.1-RELEASE-p4 amd64 system, on a SuperMicro board with:
ahci0: <Intel ICH8 AHCI SATA controller> port
0xf070-0xf077,0xf060-0xf063,0xf050-0xf057,0xf040-0xf043,0xf000-0xf01f mem
0xdfa22000-0xdfa227ff irq 19 at device 31.2 on pci0
I'm using a graid RAID1 array comprising of two INTEL SSDSA2CW160G3's with
a couple of file systems on it.
I've used 'fsck_ffs -E' on the filesystems, rebooted as single user and
done 'tunefs -t enable' for both file systems.
On a subsequent reboot I get:
"
WARNING: /: TRIM flag on fs but disk does not confirm that it supports TRIM
WARNING: /usr3: TRIM flag on fs but disk does not confirm that it supports
TRIM
"
Is TRIM supported on this configuration? - Is there any way of telling if
it's actually working?
Thanks,
-Karl
