I've configured multiple SSDs in a RAID-0 array in AHCI mode. I'd like to determine whether TRIM commands are being sent to the disks. Is there a way to monitor these commands in the kernel somewhere? I'd just like to double-check to make sure that they are, in fact, being sent.

I'm running an Ubuntu 12.04 derivative.

  • I'm curious, why have you configured multiple SSDs in RAID-0? I'm curious what kind of insane workload requires that much I/O, and yet doesn't require reliability. – derobert Dec 18 '13 at 19:46
