Powering the My Cloud Pro Series PR2100 is critical to the performance, reliability, and security of this Western Digital (WD) Network Attached Storage (NAS) device . This device is designed for professional, creative, and enterprise users who need a reliable network-based data storage and management solution.
PR2100 Power Features
The My Cloud PR2100 comes with an external power supply, designed for energy efficiency and stability. Key specifications include:
Power supply type : External power supply (AC/DC).
AC Input : 100 – 240V ~, 50/60Hz (compatible with level
IN: 19V, 6.32A.
Bring: About
This means the device can be used around the world without the need for converters, as long as you use the correct power adapter. The 19V output provides enough power to power both the NAS hardware (processor, RAM, motherboard) and two high-performance hard drives (it supports HDDs up to 10TB each, even in RAID configuration).
Energy Consumption
He c
In idle (standby): There
During data transfer or RAID operations: 25-40W.
Boot-up : Peaks up to 60-70W, especially with high-performance drives.
This efficiency is also made possible thanks to the My Cloud OS operating system, which includes power management features such as scheduled shutdown, disk hibernation and wake-on-LAN.
Cooling and thermal management
An efficient power supply must be combined with good thermal management. The PR2100 features:
An automatic cooling fan on the back, thermally controlled.
Internal sensors that adjust fan speed based on temperature.
An airflow-optimized design that dissipates heat generated by drives and electronic components.
This helps prevent overheating and extend the life of the hard drives and the drive itself.
Backup and continuous power supply
To ensure business continuity, especially in corporate environments, it is recommended to pair the PR2100 with a UPS (Uninterruptible Power Supply) . The device supports connection to a UPS via USB, allowing the NAS to:
Detect power failure.
Initiate a safe shutdown in the event of a prolonged blackout.
Prevent data or RAID volume corruption.
Conclusion
The My Cloud Pro PR2100's power supply is designed for intensive, stable, and reliable use. The use of an external power supply with a wide input range, energy optimization, and advanced management features make this NAS ideal for professional environments. To ensure long life and data integrity, it is always recommended to use original components and combine it with power backup systems.
