|---|---|---|---|
| Idle | 5.4 W | 6.2 W | |
| CPU Load | 10.8 W | 12.4 W | stress-ng (all cores) |
Full Kit (with 5x HDDs)
| State | DC measured power consumption |
AC calculated power consumption |
Remarks |
|---|---|---|---|
| Idle | 25.2 W | 29 W | |
| Suspend | 8.4 W | 9.7 W | Suspend-to-RAM, HDD in Standby mode |
| CPU Load | 31.2 W | 35.9 W | stress-ng (all cores) |
| HDD Read | 36 W | 41.4 W | dd read (no caching) from RAID6 array |
| HDD Write | 34.8 W | 40 W | dd write (no caching) to RAID6 array |
| Network Access | 33.6 W | 38.6 W | HTTP download from RAID6 array |
| Stress Test | 40.8 W | 47 W | stress-ng (all cores) + fio (all disks) + iperf |
Note
Measures were done using a Current Clamp Meter on the Helios64 12V DC input. AC Power consumption is calculated based on a AC/DC conversion efficiency of 85%.
- Meter tool : Extech 380942 - 30A True RMS AC/DC Mini Clamp
- AC/DC Adapter : 12V 10A (efficiency : 85%)
- HDD: 5x Toshiba P300 1TB (HDWD110) configured as RAID6
- Network : Connected at 2500Mb/s
- Fan : Medium speed (PWM 100)
- Battery : Charge status 100%
- OS: Armbian Ubuntu (Bionic) Linux 4.4.213-rk3399
Power consumption depends a lot on the HDDs brand and model used.
HDD Recommendation¶
We recommend HDD which are designed for NAS (Network Attached Storage). Those NAS HDD are specially conceived for reliable 24/7 operation and offers lower power consumption and dissipation, less vibration and noise, and finally better warranty. We recommend the following brands / families :
- Western Digital : WD Red NAS
- Seagate : IronWolf NAS
- HGST : Deskstar NAS
- Toshiba : NAS N300
