My home lab storage has come full circle.

I started with consumer SSDs running ZFS directly on Proxmox. After experiencing controller problems and wanting better storage visibility, I moved to a dedicated TrueNAS server serving storage to my Proxmox cluster over 10 Gigabit Ethernet.

Now I have left TrueNAS and moved back to Proxmox.

That might sound like I ended up where I started. I do not think I did.

The platform is familiar, but the setup—and my understanding of it—is different. I have addressed the controller problems, moved backup workloads off the flash pool to spinning disks and a NAS array, and rebuilt the storage configuration using the approach I developed while running TrueNAS. I also used Claude to help configure the different pools.

The biggest lesson was not that TrueNAS is better than Proxmox, or that Proxmox makes TrueNAS unnecessary.

It was that a better interface helped me develop better storage habits. Once I understood those habits, I could bring them back to Proxmox.

What the Original Proxmox Setup Got Wrong

My original storage setup used eight 2 TB consumer SATA SSDs in a ZFS pool on a Proxmox host. A six-port 10Gtek PCIe SATA controller connected some of the drives, and the host used the pool directly for virtual machines and containers.

The system was fast, but under heavier activity I started seeing timeouts and occasional drive drops.

That experience initially pushed me toward questioning the whole arrangement: consumer SSDs, ZFS, the controller, and the decision to run storage directly on the hypervisor.

Looking back, those were separate questions.

Consumer SSD endurance was one concern. Reliable drive connectivity was another. Storage visibility and maintenance were another still. Moving platforms could improve how I managed the system, but it was not automatically going to fix every underlying problem.

Replacing the 10Gtek controller with a SilverStone ECS06 significantly improved stability in my setup. That was an important reminder: a storage problem is not necessarily a filesystem problem, and a drive dropping offline does not necessarily mean the drive itself is failing.

The controller experience remains one of the most useful lessons from the entire process. Reliable connectivity comes before filesystem tuning.

What TrueNAS Actually Improved

TrueNAS gave me a storage-focused interface.

Pools, datasets, SMART tests, scrubs, snapshots, replication, alerts, and disk replacement were easier for me to see and manage together. That encouraged me to treat storage as a system that needed ongoing attention rather than something I configured once and mostly left alone.

That was a real improvement.

But I would describe it differently now than I did when I first wrote about the migration.

TrueNAS did not give my consumer SSDs enterprise endurance. It did not make ZFS fundamentally more capable than ZFS on Proxmox. It gave me a better interface for managing things I had not been doing consistently in Proxmox.

That distinction matters.

For me, the benefit was operational: clearer controls, more accessible information, and a workflow that encouraged better maintenance. Other people may already have those practices in place on Proxmox without needing a separate storage appliance.

I needed the experience before I fully understood what I wanted from my storage configuration.

Why I Moved Back to Proxmox

With the newer kernel and ZFS improvements available in my Proxmox environment, I decided to revisit the original architecture.

But the goal was not to restore the old installation and hope it behaved differently.

I rebuilt the storage configuration using the approach I had developed on TrueNAS, with Claude helping me set up the different pools. I also changed where workloads live, particularly backups.

That makes this a different setup from the one I left.

Proxmox supports ZFS as a first-class storage option. My earlier experience was not evidence that it could not manage my storage properly. It was evidence that I had not yet built and operated the configuration I wanted.

TrueNAS helped me work out what that configuration should look like. Returning to Proxmox let me apply those lessons within the virtualization platform I was already using.

My Other Reservations About TrueNAS

The technical side was not my only reason for leaving.

I also became less comfortable with the direction of the platform. What I think of as the “SSO tax,” combined with what felt like reduced visibility into how the operating system is assembled, made me question whether it remained the right fit for my lab.

Those are my concerns about the product’s direction, not proof that TrueNAS is unsuitable for everyone.

An appliance can be valuable precisely because it hides complexity. But there is a balance between making a system easier to manage and making its underlying behavior harder to inspect.

For my home lab, I increasingly wanted more direct visibility and control. The direction I perceived in the open-core model made that preference more important.

TrueNAS still helped me improve my storage practices. I can acknowledge that without wanting to keep running it.

Moving Backups Off the Flash Pool

One of the most important changes had nothing to do with the management interface.

I moved backups off the flash storage and onto spinning disks and a NAS array.

Flash makes sense for workloads that benefit from low latency and random I/O performance. That does not mean every stored byte needs to live on it.

Backup workloads can generate substantial writes and consume capacity that could otherwise serve active workloads. Moving those backups changes what the flash pool is being asked to do.

I have not established how much this will extend the SSDs’ useful life. That will require observing the write and wear trends over time.

But it is a more direct endurance-related change than moving the same workload between two platforms running ZFS.

Before trying to optimize every filesystem setting, it is worth asking a simpler question:

Does this workload need to be on flash at all?

Consumer SSDs Still Need a Thoughtful Setup

I still believe consumer SSDs can be a practical choice for a ZFS home lab.

That does not make them equivalent to enterprise SSDs. Endurance, sustained performance, firmware behavior, and power-loss protection vary by model and intended use.

The important thing is to match the hardware to the workload and understand the compromises.

ZFS also introduces its own considerations. Copy-on-write, metadata, parity, synchronous logging, compression, and application write patterns all affect the writes reaching the drives. Inside each SSD, garbage collection and flash management can create additional NAND writes.

Those are related but distinct layers. It is too simplistic to say that ZFS wears out SSDs because it uses copy-on-write.

For my purposes, the practical questions are:

Those questions matter regardless of which interface manages the pool.

What I Would Say Differently About the SLOG

In the TrueNAS configuration, I used a mirrored pair of Intel DC S3610 enterprise SSDs as a separate log device, or SLOG.

The reasoning was to use enterprise features selectively rather than replace every consumer data SSD.

That remains a reasonable approach when the workload benefits from it, but it needs careful explanation.

A SLOG is not a general write cache. ZFS already has an intent log; a separate log device changes where that log is stored. Its performance benefit depends on synchronous-write traffic and the behavior of the devices involved.

Power-loss protection on the SLOG is valuable, but it does not give the consumer data drives power-loss protection. Nor does a SLOG remove the need to write the data to the main pool.

The lesson is not “every consumer SSD pool needs enterprise log drives.”

It is to understand the workload before adding hardware intended to accelerate it.

TRIM, ARC, and the Limits of Tuning

TRIM and ARC remain useful parts of the setup, but they solve different problems.

TRIM tells supported SSDs which storage ranges are no longer needed. That can help their internal garbage collection and sustained performance. Its behavior still depends on the drives and the path connecting them to the operating system.

ARC uses RAM to cache data and metadata. It can improve read performance, but it is not an SSD endurance feature in the same sense as reducing unnecessary writes.

Neither feature belongs exclusively to TrueNAS.

The benefit I got from TrueNAS was that these controls and their surrounding workflows were easier for me to discover and manage. Bringing those practices back to Proxmox matters more than treating them as reasons to prefer one platform universally.

SMART History Is Still Worth Keeping

One practice I am keeping is historical SMART collection.

A single report is useful, but a sequence of reports can show changes that are easy to miss when checking drives individually.

I collect detailed SMART reports weekly and store them in Git. That gives me a history I can compare over time.

I am interested in changes to:

These values need to be interpreted for the specific drive model. SMART attributes are not standardized enough to assume that every manufacturer uses the same names, units, or meanings.

Historical data also helps distinguish cumulative counters from active problems. An old CRC error count is different from a count that keeps increasing.

This is useful monitoring, not a guarantee that a drive will warn me before it fails. Weekly history should complement timely fault alerts, not replace them.

Where AI Helps—and Where It Does Not

AI has become useful in two parts of this process: helping configure the storage and helping review its history.

Claude helped me set up the different pools when rebuilding Proxmox. That made the process more approachable and helped me translate the storage approach I had developed on TrueNAS back into Proxmox.

AI can also help compare SMART reports, summarize changes, and suggest things to investigate.

But AI assistance is not validation by itself.

A plausible explanation can still be wrong. A command can be syntactically valid and inappropriate for the system. A SMART attribute can be interpreted incorrectly if the drive-specific meaning is missing.

I see AI as an assistant for configuration and troubleshooting, not as a replacement for documentation, backups, alerts, or checking what the system actually did.

The useful outcome is not simply that AI produced a configuration. It is that I have a setup I understand better and can inspect more effectively.

What Survived the Round Trip

The most valuable improvements were not tied to TrueNAS:

TrueNAS helped me develop that approach. Proxmox is where I am applying it now.

That is why I do not see the return as a failed migration or a contradiction. The first move helped me identify what was missing. The second move brought those lessons back to a platform that fits my current preferences.

Final Thoughts

My earlier conclusion put too much emphasis on the platform and not enough on how I was using it.

TrueNAS gave me a better GUI for storage management. That was valuable because it helped me do things I had not been doing in Proxmox—not because Proxmox lacked a serious ZFS implementation.

Now I am back on Proxmox with a revised storage configuration, backups moved off flash, lessons from the controller problems, and AI assistance that makes configuration and investigation more approachable.

I feel better about this setup.

That is not yet proof of better endurance or long-term reliability. Those conclusions need operating history, not just confidence after a rebuild.

For now, the lesson is straightforward: consumer SSDs benefit from thoughtful workload placement, reliable hardware, monitoring, and maintenance. A dedicated storage appliance can help establish those habits, but it is not the only way to practice them.

Full circle, but set up better.

Time will tell.
