@synlogic4242@social.vivaldi.net I know, but spinning rust was half the cost vs even used SSDs; so I went this route. Here's the plan: - 2X NVME (SN850X) for special VDEV (metadata) - 1X NVME (PM983) for L2ARC - 4X HDD (26TB) for content (stripe+mirror) I was going to go RAIDZ, but this seems to be the path to high throughput.
