  • To expand on @doeknius_gloek’s comment, those categories usually directly correlate to a range of DWPD (endurance) figures. I’m most familiar with buying servers from Dell, but other brands are pretty similar.

    Usually, the split is something like this:

    • Read-intensive (RI): 0.8 - 1.2 DWPD (commonly used for file servers and the likes, where data is relatively static)
    • Mixed-use (MU): 3 - 5 DWPD (normal for databases or cache servers, where data is changing relatively frequently)
    • Write-intensive (WI): ≥10 DPWD (for massive databases, heavily-used write cache devices like ZFS ZIL/SLOG devices, that sort of thing)

    (Consumer SSDs frequently have endurances only in the 0.1 - 0.3 DWPD range for comparison, and I’ve seen as low as 0.05)

    You’ll also find these tiers roughly line up with the SSDs that expose different capacities while having the same amount of flash inside; where a consumer drive would be 512GB, an enterprise RI would be 480GB, and a MU/WI only 400GB. Similarly 1TB/960GB/800GB, 2TB/1.92TB/1.6TB, etc.

    If you only get a TBW figure, just divide by the capacity and the length of the warranty. For instance a 1.92TB 1DWPD with 5y warranty might list 3.5PBW.

    Except that they’ve ruined that too. You now need an account to view anything, so the reach of announcements is greatly diminished.

    At this point leaving shouldn’t really be too difficult, since a large portion of your audience already has; because they’ve been shut out, or have quit voluntarily.



  • Also - and I realise this might be contentious - but I’d suggest one that takes normal batteries. Mine takes 4× AAA.

    With Eneloops (or similar low-self-discharge rechargeables), can have a 2nd set that gets you back up and running in under 30 seconds, and if you get really stuck they’re sold in every corner store in the world (heck, throw a pack of Li-FeS2 batteries in the emergency kit, 20 year shelf life).

    No worrying about having the right charger cable (commonly a Micro USB, something I don’t tend to carry anymore), or remembering to charge the thing lest it go flat right in the middle of what you need to do.




  • As of USB-PD 3.1 there are now nine fixed voltages - 5, 9, 12, 15, 20, 28, 36, and 48V - and two variable-voltage modes; PPS with 3.3 - 21V in 0.02V increments, and AVS with 15 - 48V in 0.1V increments.

    Combined with a few different current limits, some of these features being optional, and then doubling down with what your cable does or doesn’t support, amazing anything gets charged at all.


  • Induction elements “cycle” on and off – hundreds or thousands of times per second […] There is no human perceptible duty cycle

    See unfortunately what you’re describing here are good induction stoves, which is not the majority of what is on the market.

    I’ve seen far too many of the bad kind, with duty cycles measured in the tens of seconds. Your 7/10 on the dial could be - like a non-inverter microwave - something in the neighbourhood of 7 seconds on / 3 seconds off. At that point they can actually be worse to use than old halogen glass cooktops, which at least remain hot during the off part of their thermostat’s cycle.

    This is not even just cheap no-name crap either, have witnessed it with big-name-brand in-bench stovetops with four-figure pricetags.

    If you’re doing something like poaching eggs (which typically calls for a wide, flat pan), you’ll actually see the water starting and stopping boiling in a cycle as it switches. Absolutely terrible.




  • do they even offer any?

    On non-LTS releases? Almost certainly not.

    You’re 100% on the money, if a broken non-LTS release - which you can still upgrade to from an earlier release with do-release-upgrade, or install from the server ISO then apt install the UI - something has already gone horribly wrong, and a couple of days wait for a re-released ISO is by far the least of your problems.




  • Agree with all these points about the Nexdock.

    We bought a bunch of them at work to be KVM consoles for computers without network out of band management, and at that they excel.

    That said, I don’t think I actually knew it had speakers, wasn’t really part of my use case :)

    It also makes me wish that USB-C connectors on GPUs hadn’t been such a short-term deal, the one-cable hookup is definitely a great thing.




  • I don’t think I’ve ever encountered a pcie card that will not function at all unless it receives it’s required lanes

    One of the few things that’d be problematic would be the x16 -> quad M.2 cards which use PCIe bifurcation.
    Lanes 1-4 from the socket are wired to the first M.2, 5-8 to the 2nd, etc.

    It would still work (by some definition of the word), but in the sense that the first M.2 drive would get 1 lane and any others wouldn’t be connected.

    (Quad M.2 boards with a “PLX” or other PCIe switch chip would work fine with 1 upstream lane serving all 4 drives)
