Hello,

Any idea if this card supports trim? I have the H220 version and it doesnt and I want to upgrade.

Thanks

I have an h240 in one of my servers. using the trim command via terminal yields 

 

root@KevinBacon:~# fstrim -v /mnt/cache
/mnt/cache: 74.4 GiB (79853207552 bytes) trimmed

 

and something similar on my other pool

 

So I guess that means yes. I thought the h220 supported trim...

LSI controllers only trim SSDs with deterministic read after trim, and with recent firmwares SAS2 models can't trim any devices with Linux, SAS3 can (on the supported models).
