I have a big pool that holds my home media, back ups, etc. I'm thinking about making an all flash pool for VM storage and would like to verify that I'm not overlooking anything.
I have read the following posts:

My understanding is that in order to get good performance without a SLOG it is necessary to set sync=disabled, which carries the risk of corrupted VMs/pool.
If that is the only risk I'm fine with that. This is for a homelab, all VMs backed up on and off site daily with Veeam(and I can live with any loss from 24 hours). My rig runs on a big UPS that is setup for graceful shutdown of VMs in extended power loss scenarios.
So my plan is to get:
(2)M.2 PCIe SSD M Key to PCIe X4 adapter
(2)Samsung SM951
Set them up in freenas as RAID 0 and disable sync writes on the pool. Than if I ever have power loss and corrupted data/pool I'll restore from backup. Got 20gbps networking in the works, so network shouldn't be a big deal. Will these adapters / SSDs work in FreeNAS/FreeBSD 9?
