June 30, 20215 yr Hi, I understand the workaround for the 30 drive limit for an Array is to create new Pools with the new disks added to the system. Is it possible to add an SSD cache to those Pools if the risk of data loss for files temporarily placed on the SSD is acceptable? This will help to improve the response time of the Pools by providing immediate write access vs. having to wait for the disks to spin up. Thank you!

Pools can act as a cache for User Shares on the main array but cannot have another pool/drive attached to them to act as a cache for the pool so what you describe is not a possibility.

However, multiple disk disk pools are using BTRFS RAID (unlike the Array) and depending the selected RAID profile, you can have a better access speed than direct Array transfers.

Yes, using RAID6 and it is faster which is great. Thanks!
