Starting Testing

Hardware Setup:

  • Odroid HC-2 including cover
  • CR2032 Backup Battery
  • WD RED 6TB (WD6002FFWX) HDD
  • SanDisk Ultra 16 GB micro sd-card

Software Setup:

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

Test:

  • 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

Iperf3 Tests:
Read: 880 Mbit / sec
Write: 660 Mbit / sec

Note:
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)

Test 1 - Full Power:
CPU Governor: performance
CPU: 4x 1400 Mhz + 4x 20000 Mhz
