HARDKERNEL ODROID-HC4
Az ODROID-HC4 egy Home-Cloud platform egy kenyérpirító formájú eszköz 2 x 3,5" vagy 2 x 2,5" merevlemezt vagy SSD-t fogad. RAID 0, RAID 1, SSD gyorsítótárazási lehetőség. Az ODROID-C4-el megegyező CPU (1.8Ghz Cortex-A55 quad core), gyors 4GB DDR4 RAM. 16MiB SPI flash chip a hasznos Petitboot rendszerindításhoz. A közvetlen PCIe to SATA bridge lehetővé teszi az akár 500MB/s átviteli sebességet is.

ODROID-HC4 is new Home-Cloud platform based on the same ARM CPU as the ODROID-C4. We adopted a 12nm fabricated energy efficient 1.8Ghz Cortex-A55 quad core processor with faster 4GB DDR4 RAM. A 16MiB SPI flash chip exists on the board for the useful Petitboot feature.
We adopted a 12nm fabricated energy efficient 1.8Ghz Cortex-A55 quad core processor with faster 4GB DDR4 RAM. A 16MiB SPI flash chip exists on the board for the useful Petitboot feature.
We decided to drop the use of USB3.0 to SATA bridge solutions (quirks, additional IO layer, etc) for the ODROID HC4. We are therefore using a more native and reliable PCIe to SATA direct bridge solutions. In doing so the HC4 board provides two SATA storage docks.
A 5.5mm DC power jack, UHS-1 compatible micro-SD slot, USB 2.0, HDMI 2.0 and 1GbE port are available on the rear side of the transparent shell case.

The toaster form factor ODROID HC4
accepts 2 x 3.5” or 2 x 2.5”” mechanical or SSD disks. You can obviously also use one mechanical and one SSD. See two examples shown below. Thanks to Linux LVM or mdadm you can combine two disks in RAID 0, RAID 1 or optimize IO with a large disk using one mechanical drive and an SSD for disk caching (LVM, bcache, etc).
Two 12TB high performance HDDs on the HC4
Two Samsung SSDs on the HC4
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:
- 4.9.230 or newer (Hardkernel stock OS version)
- Mainline kernel 5.8 or newer (Unofficial version from ODROID forum)
