December 6, 20232 yr Hey there, I'm thinking about replacing my QNAP NAS with a Unraid Server. I don't need much... 2TB usable space is quite enough for my needs. Can I run unraid with a two disk array of 2 * 2TB SATA SSD and zfs Filesystem? I like to choose zfs because of the Trim functionality - as I read it's not suggest to use xfs with SSD in an array, right? Or is full flash still not ideal for Unraid? Thank you. Chris.
December 6, 20232 yr You can make a ZFS pool, but you will still need a drive assigned to the array (plans to remove this requirement on future versions). The array drive can be a flash drive that you don't use for anything.
December 6, 20232 yr Author Did some tests.....: Array: I can setup a array with 2 drives and format it with zfs. I can configure compression on the drive & scrub scan but no autotrim. Pool: I can setup a unused array plus a pool with 2 disks. Format them as zfs, configure it as mirror. On the pool I can setup compression and scrub scan as well plus autotrom. Conclusion: If I want to use autotrim in v6.12.5 I have to setup a pool. Any plannes that autotrim for zfs-arrays will be implemented?

It should be supported in the near future, at least for a single data drive array, but a pool is usually still better since it will have faster reads due to zfs striping reads with mirrors.
December 6, 20232 yr Author okay thank you. sound's good... Then I will go for a pool with a dummy array 🙂
