I have a SSD based zpool with 5 drives 2x WD blues 1TB and 3x Crucial MX500 1TB all in mirror 1

I have turned on Trim and when i run zpool status -t ssd i get the following saying the 3 Crucial drives "trim unsupported"
Is someone able to advise what is happening. I do not see anywhere on the Crucial website saying these drived do not support TRIM.

Results below.


Code:
pool: ssd
state: ONLINE
config:

        NAME                                      STATE     READ WRITE CKSUM

Ooof...
Good thing you pasted the output of zpool status (CODE tags next time, please), otherwise I'd have to ask about this one. It's RAIDZ1.

Most likely TRIM is disabled by the OS because these disks are, to put it mildly, extremely broken and will cause absolutely monstrous write amplification if a TRIM is issued. It's a longstanding issue with the MX500 that hasn't been credibly resolved by Crucial in 6 years and several firmware versions covering multiple iterations of incompatible hardware.
