What hardware/drives do people use for their special vdevs like metadata or dedup (for those who use it)?
I'm running TrueNAS inside Proxmox and I currently have all special vdevs on virtual drives. This way I can have big SSDs handled by Proxmox, and then allocate a large number of tiny virtual drives for TrueNAS to use. But for optimum performance and safety, TrueNAS should have direct access to the physical drives?
For example my 3TB (x2 mirrored) pool currently has an 8GB metadata+small files vdev and another 8GB dedup vdev. I would have to replace these with four (mirroring) physical SSDs. It feels like such a waste to buy humongous SSDs for such tiny vdevs.
