OpenZFS 2.1 is out–let’s talk about its brand-new dRAID vdevs

I use plain mirrors in mine, but that is a really cool idea.

  I'm kinda in your camp. My typical zpool is the ZFS equivalent of a RAID10. ZFS has plenty of great valuable features, even without zraid/2/3.

>Distributed RAID vdevs are mostly intended for large storage servers—OpenZFS draid design and testing revolved largely around 90-disk systems. At smaller scale, traditional vdevs and spares remain as useful as they ever were. This couldn't be less applicable to hobbyist users. It would be interesting to see ZFS have a functional answer to Synology's F RAID.

  I thought F RAID was specifically designed for SSD?

    It is. As a home user I don't want more than 10 TB of storage, but it would be nice to have things like my game library on an SSD RAID array that can be mapped by multiple desktops and laptops. IOPS and latency are more important than throughput in terms of responsiveness and UX for general file usage. Hard drive arrays of any size are always going to have abyssmal IOPS. SSDs are also silent and low power. They're the right pick for a box that stays in a room where I live.

Still no consumer friendly NAS with ZFS. Synology is on BTRFS, Qnap has ZFS.... but their software has the worst security record. ( Arguably worst than Western Digital ) And TrueNAS mini isn't really a consumer NAS at all. The closet thing would be something like a Helios64 [1] from Kobol. But they dont seems to ship things anymore. [1] https://kobol.io https://kobol.io

  What makes TrueNAS not consumer? It seems to have a pretty thorough interface for an open source project. Is it the price range? I'm asking because I'm weighing home NAS options now and TrueNAS seems like the best option. Synology is a close second, but they are moving towards hardware whitelists and have slow maintenance of packages.

    Yes, Mainly Price. Synology has 2 Bay option and is also more of a Set and Forget it. TrueNAS is more of a Prosumer option. The DS218 with BTRFS starts at $249 and that is already consider expensive by most consumer. DS220J at $169 has the same CPU and could be modded to support BTRFS with software. ( Not suggesting anyone should do it ). If it wasn't the software segmentation I just need DS220J. Synology DS420 4 Bay starts at $499 compared to $699 for TrueNAS. And this is already going into specific needs / niche territory. I find it unfortunate, a lot of my friends are not comfortable with Cloud or dislike the idea of monthly payment. That is why I really wish Apple put out an iOS Time Capsule, unfortunately they are too busy or focused on their Services Revenue.
