I wish they would add small UPS inside (like super-capacitor or something like that) there to provide way for forced sleep when power is cut off. It's a neat small device which must be accompanied by huge bulky UPS for reliable operation.
If someone didn't know, macOS ignores fsync, so without UPS your data is not safe. Not an issue for laptops, obviously, but issue for battery-less devices.
- HenloFive 2y agoYou could use an USB C power bank, because it seems to be usb-c powered
- nicce 2y agoDoes it work 24/7 or have two power sources? Can you charge the powerbank at the same time so it will rely on the battery only when the power is down?
- quux 2y agoMany power banks support pass through charging where it powers attached devices while also charging the battery
- holycrapwhodat 2y agoIt is not USB-C powered. It needs 100-240V, 50hz-60hz AC power.
- adib 2y agoA missed opportunity though. If it’s USB-C powered, it could be even smaller and Apple could simplify its BOM by including a MacBook Pro charger with it.
- TheFuzzball 2y agoIf it was USB-C powered people would be complaining about the size of the external power supply.
- spacedcowboy 2y agoIf it only had one USBc input, how could it supply enough power for 5 USBc outputs ? Well ok, 3xTB5 + 2xUSBc, but still ?

- int_19h 2y agoIf you need to guarantee that data is, in fact, written permanently, you use fnctl(F_FULLFSYNC). FWIW while fsync() on Linux does request that the drive flushes its hardware cache, it's up to the drive whether to actually honor this request, and many don't do so synchronously (but still report success). So unless you control the whole setup end-to-end - hardware and software both - you don't actually have the guarantees.
- apitman 2y agoThanks for the explanation
- toasterlovin 2y agoIs it common for desktop computers in this size to have a built in UPS?
