  1. This is how i installed Softether VPN on my OrangePI PC2: sudo apt-get update sudo apt-get install build-essential libreadline-dev libssl-dev libncurses-dev zlib1g-dev git git clone https://github.com/SoftEtherVPN/SoftEtherVPN.git cd SoftEtherVPN sudo ./configure cd tmp sudo make sudo make install sudo vpnserver start
  2. Hi, i have seen some interest in the ASM1351 Sata to USB3.1 Gen2 controller, and as i have a USB 3.1 case with this controller i did some power consumption tests. In this case a HGST Travelstar 5K1000 1TB 2,5" HDD is mounted. Test where done with a headless RaspberryPi 3 (only power supply and the tested USB device connected), a KD302 wall power meter (measuring the complete power including the power supply) and a Drok USB 3.0 power meter (measuring only the power consumed by the USB device). "delta KD302" means the difference between headless Raspberry and the Raspberry with this USB device. USB3_BRDIGE is the empty case, without the HDD; only the bridge PCB USB3_HDD is the complete case, bridge PCB + HDD KD302 | delta KD302 | Drok --------------------------------------------------------------------------------- Power Supply idle : 0.2W RaspPi3 : 1.8W RaspPi3 + USB3_BRDIGE : 2.35W | 0.55W | 0.34W RaspPi3 + USB3_HDD : 2.75W | 0.95W | 0.67W The differences between the delta of the KD302 and the values of the Drok result probably mainly from the effeciency of the power supply (~70% ?). Also some extra power consumption of the Raspberry when a USB device is connected or the precision of the power meter could have a influence. So it seems that the ASM1351 have a lower idle power consumption compared the JMS578 and maybe also show better performance.
  3. Than you very much for your answer. So the big difference is the powered USB 2 SATA Bridge and idle/sleep power consumption of the drive. Have you also done measurements of the HC-1 with no additional disk connected, just a sd card for the system? I want to build a small server with low power consumption for usage with Nextcloud, Firefox Sync Server, Print/Scan Server, ... The XU4 /HC-1 seems to be a good compromise between performance, (idle) power consumption and software support. (compared to RasPi 3, Odroid C2) But as there is already a small Synology NAS running i think i don`t need much disk space in this small server. The HC-1 with passive cooling seemed to be a nice option, but when the idle power consumption is signifcant larger maybe the XU4 would be the better option. Using the XU4 with an emmc for the system and a 128/200/256 GB microSD as disk space for local data (although the micro sd card reader should be limited to ~40MB/sec). Or some other disk connected over USB3 with less idle consumption.
  4. Hi, in this thread it is mentioned that the minimal idle power consumption of the HC-1 is 3.7W. For the XU4 i have seen numbers from 1.7W - 1.8W for idle power consumption: https://forum.odroid.com/viewtopic.php?f=97&t=15938 I don`t know if theese measurements are done with or without including the efficiency of the power supply, and which measurement device is used. Has someone made measurements for the XU4 and the HC-1 with the same or comparable setup and can say if there is really such a big difference between them ?
