Is TRIM supported in RAID 5 on Z97 chipsets?

[Lylat1an]

I know that TRIM support was added for RAID 0 years ago, but I can't find anything confirming whether TRIM is supported in RAID 5.

My motherboard has a Z97 chipset and I'm using Samsung 860 EVO drives.

Hello Lylat1an,

Thank you for posting on the Intel Community.

We have this article that confirms that Intel® Rapid Storage Technology (Intel® RST) version 11.0 or greater supports TRIM functionality in RAID 0.

Please allow me some time to investigate if there’s any documentation available about TRIM with RAID 5. I will be posting back as soon as the outcome becomes available.

Hello Lylat1an,

Thank you for your time.

TRIM functionality is not supported with SSDs part of a RAID 5, it would be supported in RAID 0 only.

Hope this helps!

Thank you for looking into this for me.

I look forward to the day when RAID 5 gets TRIM support.
