  • That whole “1 GB per TB of capacity” is some generic rule someone made up once that doesn’t really have anything backing it up. It depends completely on your use case. If it’s mostly media storage that is rarely accessed, I’m sure that 4 GB is plenty.

    I run a beefy TrueNAS server for a friends video production company with a 170 TB ZFS array, right now ARC is using 40 GB of RAM with 34 GB free that it’s not even bothering to touch, I’m sure most of the ARC space is just wasted as well. That’s just one example of how 1 TB = 1 GB makes no sense.

    Devices like laptops, tablets and phones, usually do not have Ethernet built in, or are too mobile to make it practical to use

    What I did in the living room was plug a USB-C dock with a 2.5 Gbit Ethernet adapter into the wall outlet with a 2 meter USB-C 3.x cable.

    So I sit down in the living room and plug in my laptop/phone in to charge when I’m using it and they automatically get a 2.5 Gbit network connection. Even iOS natively supports the common Realtek 2.5 Gbit chipset.









  • I recently got upgraded to 10 Gbit fiber at home so I’ve been through researching this stuff.

    With a 3G WAN, I’d go with a 2.5 Gbit LAN - 2.5G equipment is quite affordable now. The next step is 5G but that equipment is rare, and 10G starts getting expensive.

    Do you know what router they’re giving you? What LAN ports does it have? Does it even have a 2.5 or 10G LAN port or only 1G ports?

    USB 2.5G adapters are available new for cheap and I’ve had good luck with them, even using one on a Synology NAS with an open source driver.

    The wiring is probably fine as long as you don’t have any very long runs. I’d keep it and only replace it if the links randomly drop down in speed to 1G.

    2.5G switches also aren’t too expensive. You can get one with only a few ports for the devices that can make use a lot of bandwidth (PC/NAS/Server) and plug your current switch into it for all the 1G devices like TVs, game consoles etc. The PiHole definitely doesn’t need a fast connection.


  • There isn’t a standard that is broadly-adopted, but NUT (https://networkupstools.org/) has reverse-engineered drivers for nearly every UPS out there, usually each brand has their standard so as long as the brand is supported it will work. (NUT is also what TrueNAS, Synology, QNAP, etc use internally for their UPS support)

    I’ve had good luck with using NUT with APC UPSes (both consumer models and buying used enterprise rack-mount models).

    One cool thing you can do with NUT is share the UPS state over the network, so that multiple machines can respond to the power state instead of just the machine that is plugged in via USB directly.


  • When I was following Synology communities closer, the common wisdom was that the expansion units weren’t great in either performance, stability or cost, and you were better off buying a new, bigger unit and then selling your old one used to recoup the cost difference.

    I’m also in the same position, I have a DS918+ that is full. It’s also 6 years old and probably on the tail end of getting software updates so I’m weighing my choices…
