I have new Mini X+ that I purchased from you in December 2020. SN: A1-84099. The drive LED for the L2ARC SSD flickers, showing disk activity 100% of the time. The system came to me with Freenas 11.3 U5 and the LED did NOT do this. Only after I upgraded it to True NAS Core 12.1 did the apparent continuous drive activity begin. I'm concered that this may result in unnecessary early wear to the drive.
