ODROID-XU4Q with Passive Heatsink

Most powerful little single board computer out there in this price range, I would go for the model with a fan, as the passive heatsink model can get the cpu speed throttled quite often, if I bought them again I would get the version with the fan, but over all, one beastly board!

Way, way, WAY better than my RPi3 for emulating. It can handle PSP with no problem, even N64 and Dreamcast. After using the XU4 I do not understand the popularity of the RPi3, you get way more performance for your money with the XU4.

This is my 2nd Odroid XU4 SBC. It is much better designed than the active heat-sink model by adding my own cooling fan:https://www.amazon.com/Noctua-Cooling-Bearing-NF-A4X10-FLX-5V/dp/B00NEMGCIAThe fan is 40mm x 40mm, the same size as the passive heat-sink. it comes with 4 rubber vibration-compensators. I can use them to attach the cooling fan easily on the top of heat-sink. (see my pictures)I also bought 1TB 2.5 inch hard drive, using Y-type USB3 to SATA connectors to attach the hard drive to USB 3 (for data) and USB 2 (for power) on XU4, notice that USB 3.0 on XU4 is OTG USB 3 design, not normal USB 3.0. it can only power on an USB thumb drive,it does not have enough current to power on a portable hard drive. I choose 5V 800mA hard drive. I cannot guarantee most 5V 1A portable hard drive can spin up with XU4, but 5V 800mA works well with manufacture 5V 4A DC adapter. (see my picture for hard drive model)I download and installed Odroid official Ubuntu 16.04 for XU4. also installed and configure SAMBA service, Seafile and Pydio on itUpload 11GB large file to my XU4 from other machine in my local network with SAMBA, I can achieve 52MB/s upload speed.(see my picture)Upload the same large file to Seafile Server on my XU4 (I moved Seafile data folder to 2.5inch drive, not on SD card). I can achieve very constant 47MB/s upload speed..(see my picture)Upload the same large file to Pydio Server on my XU4 (I moved Pydio data folder to 2.5inch drive, not on SD card). I can achieve 49.9MB/s upload speed..(see my picture)Using my own bash shell script, I can see idle CPU temperature is around 54 °C, during upload, it becomes 65 °C. no CPU throttling. (see pictures)Really happy with it.

I upgraded my trusty ODROID C1+ that served as a torrentwatch-xa automatic torrent downloader for a couple of years to this awesome fanless XU4Q.It is MUCH faster than the C1+, especially with the USB 3.0 port, to which I attach an external 2.5 SATA hard drive.I guess my only complaint is that I wish it had four USB 3.0 or 3.1 ports, but this would probably increase the price considerably.

Super micro ordinateur, capable d'avoir plusieurs fonction.Par contre le dissipateur de chaleur ne dissipe pas énormément la chaleur, vaut mieux opter pour le XU4 avec ventilateur

Got my odroid xu4 between 3 - 17 days early (quoted delivery time was june 4 - 14) which is a big plus in my books. Loaded up my odroid with open media vault and it works like a charm. I have no problems with it and its way better then the raspberry pi 3 b+ by far. Works as advertised and i cant wait to buy another one.

Ricevuta una nuova scheda. La prima aveva avuto problemi nella spedizione. Peraltro ottimo il venditore Recovery Mobile SL. Risponde velocissimo ed e' molto gentile.Sulla scheda: la consiglio assolutamente. Avevo una Radxa gia' piu' veloce di un Raspberry. Ho migrato su Odroid XU4 il mio sito web, il servizio di monitoring telecamere Zoneminder, il servizio NAS e il servizio DLNA.L'odroid XU4 e' un missile. Grazie ai suoi 8 processori, la LAN/WAN ad 1 Gbit e USB 3.0 e' un missile!Un altro aspetto sul quale non contavo e' il supporto da parte di Odroid. Esiste una sito wiki di Odroid ben fatto ed anche il forum ottimamente seguito dagli amministratori che rispondono in giornata.Sono passato da 14.04 su Radxa all'ultimo 18.04 su Odroid.Peraltro una funzionalita' che non avevo su Radxa, posso vedere i video su youtube molto fluidi. Su Radxa a causa del processore video Mali vecchio ed incompatibilita' mai risolte il video era a scatti.Scivero' meglio in fututo, ma mi sembra quasi un Pc da tavolo.Ottimo Odroid XU4. Consiglio l'acquisto e consiglio l'acquisto da Recovery SL che beneficia garanzia dei prodotti gestiti da Amazon e costo molto piu' basso rispetto all'altro distributore.OTTIMONOTA: state solo attenti all'alimentatore. deve essere ben dimensionato. Se comprate un alimentatore switching per avere maggiore amperaggio rivolgetevi a Mean Well e come connettori non comprate assolutamente le cineserie per telecamere (che purtroppo sono anche su Amazon).Ho visto connettori degni solo su Amazon US. Il cavo deve essere di sezione oppotuna per non avere cadute di tensione elevate. L'Odroid XU4 puo' richiedere anche 4 A!! Quindi anche con resistenze piccole, potete avre cadute di tensione sui connettori (V=R*I) sensibili. Se l'utilizzatore e' una scheda digitale puo' spegnersi/resettarsi.Alla fine me li sono fatti io i cavi comprando un connettore barrel ed utilizzando cavi miei di sezione opportuna.

Good alternative to the Raspberry Pi. Much faster, double the memory, active community. Complicated setup, but ETA PRIME and NovaSpirit Tech on Youtube provide great videos for setting it up. Mine has been 24/7 reliable as a miner with a fan replacing the passive heat sink. No built-in Wi-Fi is questionable, but easily solved by various dongles. Toggle switch allows booting between eMMC with Android and microSD card with Linux. Suspect the design is for headless operation, so pay attention to the blue LED and have patience as nothing is shown on screen until it needs to be.

Vor 4 Tagen kam der ODROID-XU4Q und das Netzteil an. Sofort an den Fernseher angeschlossen, die von mir vorbereitete MicroSD, Strom und den Wireless Tastatur Dongle eingesteckt. Enttäuschung.Da geht gar nichts. Image neu aufgespielt, nichts. Anderes Image, nichts. Android 4.4 - das geht, aber auch wenn es cool ist, das brauch ich nicht. Wenigstens ist der Odroid nicht defekt.Dann hab ich endlich die Seite mit den aktuelleren Images gefunden. Ubuntu Mate 16.04 LTS - funktioniert super. RAM Verbrauch bei 1GB. Die 8 Cores kommen mit den Anforderungen bestens klar bei denen der Raspi ins Schwitzen kam. Internet surfen mit Chromium wird erst ab 10 Tabs ein wenig zäher. Youtube im fullHD Vollbild ist nicht immer flüssig. Das war aber auch nicht das Ziel.Die Festplatte (WD My book 4TB) schafft ~110MB / sec - das ist schon zehn mal so schnell als am Raspi. Daher gleich noch eine 3 und eine 2 TB Platte angesteckt. Da wird es auch schon wieder eng, denn der ODROID hat ja nur 2 USB3 und eine USB2 Schnittstelle. Kein Bluetooth. Also muss der Remote Zugriff ordentlich funktionieren. Hab dafür ssh, xvnc und xvfb installiert. Letzteres, damit eine x11 Session geöffnet wird, obwohl ja kein Bildschirm angesteckt ist und sich niemand anmeldet. Jetzt kann ich mich vom Handy oder Tablet über einen SSH Tunnel anmelden und hab überall die GUI.Der Kühlkörper wird im Dauerbetrieb warm. Ein Gehäuse würde ich nicht rundherum geben. Wenn, dann nur mit aktiver Kühlung. So hab ich den ODROID samt 3 Platten in den Keller verfrachtet. Da ist es immer schön kühl und das Surren der Platten ist auch egal.Die GPIO werde ich nicht am Odroid verwenden. Damit wird man unflexibel. Für diese Funktionen braucht man keine Rechenleistung, dazu setze ich lieber die NodeMCU ein, welche ich über WLAN steuern kann. NodeMCUs sind physisch vom Server getrennt, sind nicht angreifbar und haben auch genug GPIOs für Relais.Mein Fazit: der Preis ist um einiges höher als ein Raspberry3. Dafür hat man dann aber auch einen richtig flotten, energiesparenden Server, dem der Speicher nicht mehr so schnell ausgeht.
