What RAID levels is TRIM supported on IRST?

[NWagn]

I know over the years features have been added to IRST regarding TRIM (I found an article in 2012 noting that TRIM support was added to RAID-0 on IRST 11.x+ and 7-series chipsets), but what is the state of TRIM support on the current IRST drivers? I really can't find anything suggesting anything beyond the RAID-0 announcement, but it seems like by now it would at least support RAID-1, if not RAID-10 as well. In particular I'm looking at an H270 chipset with 6th gen processor.

MagicNeil: Thank you for joining the Intel® communities support.

This feature provides support for all solid state disks (SSDs) in your storage system that meet the ATA-8 protocol requirements and are not part of an array. This feature optimizes write operations, helps devices reduce wear, and maintains unused storage area on devices as large as possible.Beginning with the Intel® 7 Series chipset the driver supports TRIM on SSDs in a RAID 0 configuration.Regards,Alberto R.

Thanks for taking the time to reply Alberto!

To be clear, the ONLY RAID configuration that passes TRIM commands to the disks is RAID 0, even on newer controllers?

MagicNeil: You are very welcome. That is correct, it only works with RAID 0.
