Would there be any performance gain from storing Hyper-V VHDX on a TrueNAS to take advantage of ZFS ? (alien.top)

Hi /r/homelab

I've a single HyperV host running Windows Server 2022 setup with DDR5 64 GB of RAM running on a custom built ASUS motherboard with Intel Core i9-12900K and x2 1TB NVME drives.

Currently I create my Hyper-V VMs and store the VHDX on DAS (directly on the NVME drives) as opposed to storing them within a physical or virtual NAS.

I'm wondering if I create a virtual TrueNAS VM (btw I do not have experience with NAS or TrueNAS) would there be any performance gains from doing so by leveraging ZFS instead of the native NTFS ?

Sorry I'm really new to this. Thanks so much in advance.

There will be no performance gain even if you passthrough NVMe drives to that TrueNAS VM as you still need connect storage back to Hyper-V (iSCSI or SMB). You'll just add more latency.
