    I would recommend something like a Pi as well, but it looks like you’re going to have to take it down to 5v. Maybe a NUC might be better.

    But if you really want 20 TB, you’ll need to buy two drives at least 10 TB, and you’ll want them to be SSDs for the low power requirement. So that means you’ll need a device with two SATA ports, because I don’t think anyone makes NVMe drives that big. Oh, and be ready to pay a few thousand for each drive. Also you’ll want to keep one drive offline, in an ESD bag in a dry bag. So maybe one will be USB.

    But for real low power, I’d suggest just plain turning it off. Booting doesn’t take that long any more. Or maybe suspend to disk, if you can find a system that supports it.

    But overall, I would suggest reevaluating how important these things are to you. Generally, lots of electronics and nomadism don’t go together. Have you considered books? I’m sure you can find people to swap with when you’re in port.

    Tell the ISP you’re signing up with that there’s no drop for their service, and have them run a new one to the office. Check your local laws about touching their wire or box on the outside of the house before removing it.

    Also, it’s really easy to patch holes in drywall with a little joint compound and matched paint.

    Otherwise, MoCA and powerline ethernet can work. Modern wifi is pretty good too, though consider walls, etc. between points A and B and which frequency you’ll be using.

    I myself have gotten answers along the lines of, “why aren’t you acting more like a paid IT person?” and it’s a little off-putting.

    We’re all hobbyists (though some of us do it profesionally too). Wanting your service to be reliable is a fair assumption. If you don’t care if Jellyfin goes down while your girlfriend is trying to watch The Bachelor, or if you accidentally delete all your photos with no backups, then just say you accept that risk and nobody should give you a hard time.


  • It’s possible to convert drives to RAID in-place… but strongly discouraged.

    Since OP will have a blank drive, they could play musical chairs by setting up a new RAID on the new empty drive, copy data from one drive, wipe that drive, grow the array, copy data from the third drive, wipe, grow… But that’s going to take a long time, and you’ll have to keep notes about where you are in the process, lest you forget which drive is which over the multiple days this will take.








  • Server PSUs are designed to be identical and work on parallel (though depending on platform, they can be configured as primary/hot spare, too). I’d be concerned about potential difference in power, especially with two non-matching PSUs. It would probably be fine, but not probably enough for me to trust my stuff to it. They’re just not designed or tested to operate like that, so they may behave unexpectedly.


  • PCIe is absolutely plug and play. Cards have been PnP since the ISA era. You probably meant hot-plug, but it’s hot-pluggable too: https://lwn.net/Articles/767885/

    Any buffered data will sit in the buffer, and eventually be dropped. Any data sent to the buffer while the buffer is full will be dropped. I’m not intimately familiar with communicating with GPUs, but I imagine the only buffers are in the GPU driver (which would either handle the removal or crash) or in the application (which would probably not handle the removal and just crash). Buffering is not really where I would expect to see a problem.

    That said, a GPU disappearing unexpectedly will probably crash your program, if not your whole OS. Physical damage is unlikely, though I definitely wouldn’t recommend connecting two PSUs to one system due to the potential for unexpected… well, potential. Inrush current wouldn’t really be my concern, since it would be pulling from the external PSU which should have plenty of capacity (and over-current protection too, I would hope). And it’s mostly a concern for AC systems, rarely for DC.
