BoomerNation Posted November 14, 2021 Posted November 14, 2021 (edited) Hello good folks! I am about to dive into the unraid world and I have a couple of questions with regards to TRIM etc that I would really appreciate your help with answering. I have 8 x 8TB spinning drives that will be my main storage. These are connected directly to mobo. I also have about 16 Intel S3710 800gb. Have ordered a 16 bay SSD cage for these. I was thinking of splitting these drives in 2 with 8 used for cache and 8 used for games. My questions are as follows: 1. Which 16i HBA's support TRIM under unraid? I seem to have a hard time finding out exactly what is needed. 2. Do my ssds support TRIM under unraid (I read there were a couple of different ways of implementing TRIM, namely DRAT/DZAT)? 3. Anything else I need to think of in this regards such as which fs to use? Or with regards to anything else? I appreciate all input and support and pardon me if this has been answered before but I have tried to look for answers myself without it making me any wiser.

LSI 93xx HBAs support trim, but only on devices with deterministic trim support. 15 hours ago, BoomerNation said: Do my ssds support TRIM under unraid (I read there were a couple of different ways of implementing TRIM, namely DRAT/DZAT)?

So is 9300 the only card to support TRIM in Unraid, ie. 9400 does not? Thanks for that post. I don't have any spare ports on my mobo at the moment, so I might have to check this on another sever/computer. But there is no quick and easy overview saying which drives have deterministic trim support? Edit: found these 2 pages which seems to indicate that my drives do indeed support it: https://www.truenas.com/community/threads/ssd-dying.95907/ Deterministic read ZEROs after TRIM will do right? https://www.thomas-krenn.com/de/wiki/Intel_DC_S3710_Series_SSDs Edited November 15, 2021 by BoomerNation Quote

I would expect it does, but don't have one to confirm nor do I remember someone else confirming it. 55 minutes ago, BoomerNation said: Edit: found these 2 pages which seems to indicate that my drives do indeed support it: Looks like it. 1 Quote
BoomerNation Posted November 15, 2021 Author Posted November 15, 2021 Again, thanks for taking the time to help out. I think I might just have to bite the bullet and buy the fossil 9300-16. The return process will be too expensive if the 9400-16i doesn't support it so unless someone else confirms compatibility, I'm not going to take the chance. Quote
