April 4, 20251 yr Hi Forum! a few weeks ago I've discovered Unraid and used with my 2014 Mac mini. The Mac has two internal SSDs: - 128 GB (Apple proprietary) PCIe SSD: used as Cache Device - 2 TB SATA SSD: used as Array Device Now I've ordered new system based on standard hardware. It comes with a 512 GB NVMe SSD and room for some more drives. I've currently three shares: appdata, system and my data network share and all set to use Array as primary storage. As I cannot move the cache drive to the new hardware, my plan is to connect only the Unraid USB stick and the 2 TB SSD to the new machine and add the new 512GB NVMe SSD to the Cache Pool. Is this a plan that will work (as the cache drive should not contain any) data or is there something more to consider? Thanks a lot! Frank
April 4, 20251 yr Community Expert You might consider no array, and just put your storage SSD as another pool. SSDs in the array cannot be trimmed. Unraid V7 does not require an array. Mover can move between pools. And all pools are part of user shares. So, everything would work like before, but your SSD could be trimmed. And any pool can be multidisk with redundancy if you need to expand.
April 4, 20251 yr Author Is it then possible to stop the array, unassign all the drives from their current pool/array and assign it to a new pool?
