Something occurred to me while watching some news yesterday. It won’t take ICE raids removing people from farms for the effect to materialize. The fear from raids will cause people to stop showing up for work at the farms before that. That’s why I think we’ll see the effects on food prices quicker.

Don’t they have to rework their refineries in order to replace Canadian oil? Instead the refineries currently working with Canadian oil are specifically built to process dillbit, due to having been built to use Venezuelan dillbit originally.

I suppose Albertans in oil and gas should call Danielle and tell her to stop the clown tricks and join Team Canada now.

No disagreement.

While I do not want to vote for Singh, the leader, I would vote for the NDP candidate in my riding if the polls don’t show them far behind.

Well done keeping your composure while explaining!

I’ll try 3tsp tomorrow. 👍

I’m dying here. 🤣

• Lenovo ThinkCentre / Dell OptiPlex USFF machine like the M710q.
• Secondary NVMe or SATA SSD for a RAID1 mirror
  • Use LVMRAID for this. It uses mdraid underneath but it’s easier to manage
• External USB disks for storage
  • WD Elements generally work well when well ventilated
  • OWC Mercury Elite Pro Quad has a very well implemented USB path and has been problem-free in my testing
• Debian / Ubuntu LTS
• ZFS for the disk storage
• Backups may require a second copy or similar of this setup so keep that in mind when thinking about the storage space and cost

Here’s a visual inspiration:

Yes, yes I would use ZFS if I had only one file on my disk.

OK, I think it may have to do with the odd number of data drives. If I create a raidz2 with 4 of the 5 disks, even with ashift=12, recordsize=128K, the performance in sequential single thread read is stellar. What’s not clear is why this doesn’t affect, or not as much, the 4x 8TB-drive raidz1.

Found the bit counter

Here’s the box test thread if you’re curious. 😊

I think I’ve seen this hypothesis too and it makes sense to me.

If I’m building a new AMD system today, I’d look for a board that exposes more of the chipset-provided USB ports. Otherwise I’d budget for a high quality 4-port PCIe USB controller, if I’m planning to rely a lot on USB on that system.

This article provides some context. Now I do have the latest firmware which should have these fixes but they don’t seem to be foolproof. I’ve seen reports around the web that the firmware improves things but doesn’t completely eliminate them.

If you’ve seen devices disconnecting and reconnecting on occasion, it could be it.

I’ve been on the USB train since 2019.

You’re exactly right, you gotta get devices with good USB-to-SATA chipsets, and you gotta keep them cool.

I’ve been using a mix of WD Elements, WD MyBook and StarTech/Vantec enclosures (ASM1351). I’ve had to cool all the chipsets on WD because they like bolt the PCBs straight to the drive so it heats up from it.

From all my testing I’ve discovered that:

• ASM1351 and ASM235CM are generally problem-free, but the former needs passive cooling if close to a disk. A small heatsink adhered with standard double-sided heat conductive tape is good enough.
• Host controllers matter too. Intel is generally problem-free. So is VIA. AMD has some issues on the CPU side on some models which are still not fully solved.

I like this box in particular because it uses a very straightforward design. It’s got 4x ASM235CM with cooling connected to a VIA hub. It’s got a built-in power supply, fan, it even comes with good cables. It fixes a lot of the system variables to known good values. You’re left with connecting it to a good USB host controller.

WD PCB on disk

I thought about it, but it typically requires extra PCIe cards that I can’t rely on as there’s no space in one of the machines and no PCIe slots in the other. That’s why I did a careful search till I stumbled upon this particular enclosure and then I tested one with ZFS for over a week before buying the rest.

You want ASMedia ASM1351 (heatsinked) or ASM235CM on the device side 🥹

This box has 4x ASM235CM and from the testing I’ve conducted over the last week it seems rock solid, so long as it’s not connected to the Ryzen’s built-in USB controller. It’s been flawless on the B350 chipset’s USB controller.

Thanks for the warning ⚠️🙏

This isn’t my first rodeo with ZFS on USB. I’ve been running USB for a few years now. Recently I ran this particular box through a battery of tests and I’m reasonably confident that with my particular set of hardware it’ll be fine. It passed everything I threw at it, once connected to a good port on my machine. But you’re generally right and as you can see I discussed that in the testing thread, and I encountered some issues that I managed to solve. If you think I’ve missed something specific - let me know! 😊

That was the cheapest option. 🤭
