    An old PC is the best NAS, even if you choose a dedicated NAS box it’s likely that you’ll want to “upgrade” to an old PC in a year or two. Unlike premade NAS boxes you have full control over the software and can modify the hardware as needed. You can undervolt/underclock to save power too, so the main difference is only the physical space it takes. Having the ability to run docker containers and VMs on the same device is incredibly useful, and you’ll get significantly faster transfers despite the drastically lower cost.











  • Even if possible, a $50 old office PC will be more reliable with no risk of the Android OS killing whatever software you end up running on it. And you can use SATA HDDs directly with such a setup. The power consumption is likely a bit higher than running on a phone, but for the ability to run any docker container out there it’s likely a worthwhile tradeoff. Alternatively if you can hunt down an Atomic Pi or similar old atom based SBC you can trade some performance for power savings while still running an OS truly intended for networking.




  • The USB type C connector itself is amazing. I’ve never broken the physical connector, the problem is electrical only. The connector is capable of delivering a very high 240W of power, but the device/charger negotiate the power and voltage requirements to find the highest both can support.

    But there are actually four parts of the system limiting the negotiated power:

    • The maximum power the charger can deliver
    • The maximum power the charging device can receive
    • The maximum current the cable can deliver
    • The signaling protocol used to negotiate the highest supported power across the link

    The problem ultimately comes from the negotiation as many devices don’t use USB-PD (the theoretical “standard” for this) to save cost or allow different electrical configurations. This can lead to chargers incorrectly identifying devices as capable of accepting higher voltages than they can. Or devices can incorrectly identify themselves as capable of accepting higher voltage than they actually can.

    If you’re using reputable decides from reputable companies using the included charger/cables, this will never be an issue. It’s only problematic when you want one charger for all your USB type C devices, as it now needs to support multiple communication protocols and voltage standards, hoping that no device identifies itself incorrectly.
