ODROID-HC4-P KIT

Deze nieuwe kit bestaat uit een ODROID HC4 Board, een behuizing gemaakt van een PCB waarin je twee 3,5-inch HDD's horizontaal kan monteren, koelventilator, kabels en bouten.
Het is je eigen netwerkopslagapparaat dat je met veel plezier zelf kunt maken, en de Petitboot-functie van de HC4 en verschillende nieuwste OS-ondersteuning kunnen zonder enige wijzigingen worden gebruikt.

Houd er rekening mee dat dit product geen opslagapparaat van 2,5 inch kan monteren.
Opmerking! Deze KIT bevat GEEN OLED+RTC voor HC4-P. (Individueel verkocht)

SATA interface performance

We connected a SATA SSD to the HC4 platform and measured the storage IO throughput. We could observe 390~420MB/s transfer speed which is not saturated at the maximum level ~500MB/s which is quite good for many applications.

SMB/CIFS network file transfer performance over the Gbit Ethernet connection

As shown below Windows OS client shows a sustainable 100+ MB/s transfer speed when we download/upload large files.

Power Consumption

Note 1: ST2000DM006 spin-down power consumption is 0.75W per HDD. Therefore, the HC4 idle mode power consumption is about 4W.

Note 2: Power consumption in Active state is tested while copying huge files through SAMBA service.

Note 3: Wake-up sources for the Suspend mode: Wake-on-LAN, IR remote receiver and RTC Alarm.

Software Support

Petitboot can find the OS on the SD card, the HDD or the SSD. So even if you do not have an SD card but you have a plugged-in HDD or SSD that has an OS installed, Petitboot will boot the HC4 using the OS from the HDD or SSD. Debian/Ubuntu OS can run with the Hardkernel’s preinstalled OS image or Debian/Ubuntu Netboot Installer which you can obtain from the ODROID forum.

Supported Linux kernel versions are:

1. 4.9.230 or newer (Hardkernel stock OS version)
2. Mainline kernel 5.15 or newer (Unofficial version from ODROID forum)
