Consists of ODROID-HC4 board, a case made of a rigid PCB that can mount two 3.5-inch HDDs horizontally, cooling fan, cables and bolts. It’s your own network storage device that you can enjoy creating yourself, and the HC4’s Petitboot function and various latest OS support can be used without any changes. Please note that this product cannot mount any 2.5-inch storage device.
Note! This KIT does NOT include OLED+RTC for HC4-P. (Sold individually)

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.
Helios LAN Test Result
Samsung 860 EVO 250GB SSD
Seagate Barracuda 2TB HDD (ST2000DM006)
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.
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 5.15 or newer (Unofficial version from ODROID forum)
