Yet another Reddit refugee from the great 3rd party app purge of 2023. This account is mostly for learning how Lemmy works and may be purged once I get around to hosting my own instance.

Obligatory fuck /u/Spez.

  • 2.5 is still really new in the networking space and nobody has hit economies of scale yet. I very much also want to build out my home LAN to be entirely 2.5g compatible since 1g is limiting for my NAS use case (video storage), 10g is overkill and not supported by my client devices, and I only need 16/24 ports. but good God the hardware just isn’t reasonable yet.

    You pretty much have to bite the bullet if you really want 2.5 right now. What might honestly be worthwhile is finding a used enterprise 1g switch with the number of ports you need, and will still be “enough”, as those can be had for only a couple hundred dollars. Sit on that for 2-3 years until the 2.5g and 5g hardware market starts to fill out and you can decide how badly you need 2.5g then

    Really. Anything branded from Samsung or Crucial(Micron) is going to be fine. They are the top producers of NAND, produce high quality products, and stand behind warranties. But you are gonna pay out the nose for the privilege of enterprise grade hardware.

    You might just be buying lower quality consumer SSD’s though, since even they should be able to handle a surprising amount of abuse.











  • Pi’s have kinda garbage IO. You’re limited to USB only which is a shared bus (so if you’re saturating one hard drive, the other drives won’t be able to do shit and I dislike it) you’re also required to boot from SD card on a Pi, and OS level writes tend to kill SD cards frequently.

    The Orange Pi 5 that I have technically has a PCIe NVME M.2 slot that runs at PCIe 2.0x2 iirc. I’ve not done it with mine yet, so I can’t guarantee compatibility, but that can theoretically be split using a m.2 to SATA controller adapter like that

    But at that point and cost the Rockpro64 look like a legitimate option, since PCIe to SATA adapters using a 4x slot exist all over the damn place.

    Honest opinion though: look for used office PC sales or government/school district clearing sales. I’ve gotten a stack of older 2nd/3rd gen intel Core machines at $50 a pop that are plenty fast for light home server use and have full fat motherboards for connecting up a bunch of SATA devices. They’re a little more power hungry- expect 50W or more at idle when you have drives spinning - but they simplify setup a lot, they package nicely since you can put the drives inside, and the power supply is built in.


  • Is there trim in the crease or it is a sharp corner? If there is trim and its not painted clean over, you can cheat and use paperclips. Fold the long leg out straight, so its horizontal, and the short U curl down at a 90, so it forms a hook. If you stick the horizontal wire in behind the trim itll usually wedge in without damaging the trim or paint visibly and hold enough for a cat5e.

    If no trim, the sticky hangars are probably the best. Be careful not to buy cheap ones that might fall down, leave residue, or stick too hard and rip the paint off when you go to remove it.



  • There’s no such thing as overkill, only extra overhead to do more things with. Hell, if you found yourself with a ton of excess resources and good cooling, you could run a distributed computing project like BOINC on some of the spare cores and help out some scientists.

    You wouldn’t see much of a bump in CPU performance, 6cores to 8 cores with a 200mhz clock speed improvement isn’t ground breaking.

    Going to 8gb of memory will give caching benefits.

    But… That’s all well and good. However. What I found the most beneficial on a OPi 5, and the entire reason I bought it over other boards, is the onboard NVME m.2 slot. Yes, the orange pi 5 can support 2230 and 2242 M.2 NVME drives at PCIe3.0x1 speeds, and it makes a WORLD of difference in performance. Like you would not even believe how fast compiling and installing software becomes when it’s not bottlenecked by the ~500 iops an SD card can struggle through. SD cards are ungodly slow, and OS level writes tend to kill them every few months (they’re not designed to handle that kind of work). Even the cheapest aliexpress M.2 drives, which I bought a 512gb KingSpec one for like $16, blow SD cards out of the water, and will last for YEARS with a typical pi’s workload compared to the few-months of an SD card. Plus they’re big enough to even do a bit of file hosting on.



  • You’re welcome to call their tech support and ask about using custom routing hardware, at least. It’s possible they already have an approved list of SFP’s that they would be willing to work with, just don’t hold your breath since they probably want (and need) to have management control over the entire router endpoint, not just the module.


  • 2GB of memory is fine for openWRT. Routing is surprisingly light tbh, consider that most all home/SOHO routers run integrated SoC’s with <256MB of memory.

    routing speed is more dependent on CPU +cache speed

    i’d eat my boot if a residential ISP let you run your own SFP fiber module. they have to pretty tighttly control those things to keep signal levels right and have wavelengths in the right spots. plus they’ll need to upstream reconfigure it somewhat frequently as the local network changes and if it’s not their hardware, they’ll get mad.


  • I highly doubt homeassistant will ever abuse the pi4 CPU enough to make active cooling necessary. As long as you have a heatsink of some form on the SoC you’ll likely be perfectly fine. Obviously monitor it for core temps once installed.

    Remember the Pi uses the entire PCB copper ground plane in the board as a heatsink too.
