Hi everybody,

I'm a new FreeBSD user,

I recently installed FreeBSD 13.2p8 on an old Thinkpad T400 laptop with a "Samsung 850 EVO" SSD,
I found the following lines in my dmesg:

Code: 
ada0 at ahcich0 bus 0 scbus0 target 0 lun 0
ada0: <Samsung SSD 850 EVO 500GB EMxxxxxx> ACS-2 ATA SATA 3.x device
ada0: Serial Number xxxxxxxxxxx
ada0: 300.000MB/s transfers (SATA 2.x, UDMA6, PIO 512bytes)
ada0: Command Queueing enabled
ada0: 476940MB (976773168 512 byte sectors)
ada0: quirks=0x3<4K,NCQ_TRIM_BROKEN>

I'm concerned by the line that says "Trim Broken", because I keep some important files in here and I would like the SSD to be in good shape..
What does it mean exactly ? Is it something I should worry about ?

( by the way, if i run
zpool trim zroot it runs without giving errors )

How old is that drive? the 850s appeared ~2015 IIRC... Check SMART data!
Also the EVOs never were known for their good reliability - get a PRO variant if you care about that. We never had one of those PRO SSDs (SATA) fail in our clients, but several EVO showed data corruption after ~3-4 years...

As for the quirks message: there's nothing you can do about that. The firmware of those drives is borked and samsung never fixed that, hence there was this workaround put in the driver, that won't allow the drive to queue TRIM commands.

Yes, the drive is from 2017, but the TBW count is still low and SMART reports that everything is good (I also did a short and a long SMART test, all good) the drive itself never gave any problem.
Hopefully in the future I can afford a mirror with a couple of enterprise-grade drives :)
