Odroid HC-2

:smiley: Hardkernel released the Odroid HC-2 (same as HC-1 but for 3 1/2" hdd drives)

As fast as i have mine in hand, i’ll update this thread with further news.

Now i can build up my home cloud with 6-10 TB space :mrgreen:


  • at Pollin it will be available at begin of february, as i got informed.

:mrgreen: My HC-2 is just arrived :slight_smile: more news i can give you later.

As far as i got it tested, the actually odroid image for xu4/hc1 works also on HC-2 out of the box.

great work

Starting Testing

Hardware Setup:

  • Odroid HC-2 including cover
  • CR2032 Backup Battery
  • SanDisk Ultra 16 GB micro sd-card

Software Setup:

  • Official Dietpi Image Odroid XU3/XU4/HC1 (DietPi_OdroidXU4-ARMv7-Jessie.7z)
  • Samba


  • Sysbench (similar results as HC-1)
  • hdparm -t /dev/sda = around 126 Mb / Sec.

What throughput numbers do you get when moving large files between Windows and HC2 with Samba? Can you provide Windows Explorer screenshots for uploading and downloading? Interested especially in a performance drop after some few hundred MB have been written or read since I’ve seen this on few other boards already.

I’ll will test it, today evening, then upload some screenshots.

Jep, XU3/XU4/HC1 image works well, as HC2 is based on XU4 device as well. We already updated the download page to reflect this: http://dietpi.com/#download

First Test:

Result W7 → Samba → HC2:
Result HC2 → Samba → W7:
Iperf3 Tests:
Read: 880 Mbit / sec
Write: 660 Mbit / sec

Temperature about 53-67 °C as cpu mentioned it.
Here i wil build first up a better case including fans, as the WD RED 6TB brings too much heat to the standard case.

Cooling Issue - Tests:

1x 40mm Fan on Headspreader = 53-57 °C (idle/30%load)
1x 92mm Fan on Headspreader = 42-47 °C (Idle/30% load)

Next Step: New Case, with 2x92mm Fan or 100mm perhaps

Is your hardware defective? Just asking since with OMV the numbers are above 100 MB/s

See ‘NETWORK STORAGE PERFORMANCE’ here http://www.hardkernel.com/main/products/prdt_info.php?g_code=G151505170472 or https://forum.openmediavault.org/index.php/Thread/19618-OMV-3-for-ODROID-XU4-HC1-HC2-MC1/

Can you give it a quick check with OMV? First steps are outlined by Hardkernel here: https://wiki.odroid.com/odroid-xu4/software/omv_nas/eng/01_beginning

I’ll try it next week, then can give you a review.

The Cooling of HC-2 doesn’t work as it should!, see Benchmark results.
For Tests i glue 2x 100x100mm Fans direct on the Heatsink and powered them external.

Room Temp: 21 °C
HDD: in sleeping mode (so less heat from it)
