Description

The WD20EURS is a 2TB 3.5" SATA hard drive from Western Digital's GreenPower series, designed to reduce power consumption in desktop systems, NAS enclosures and DVR applications. The drive operates at 5400 RPM and uses Advanced Format technology with 4KB sectors rather than the older 512-byte standard, improving efficiency and storage density across the 2TB capacity.

This drive suits desktop PCs requiring additional bulk storage, home servers running media libraries, and CCTV DVR systems recording continuous video feeds. The WD20EURS draws 5VDC at 0.70A and 12VDC at 0.66A under typical load, making it more power-efficient than performance-focused 7200 RPM drives. The GreenPower designation indicates Western Digital's focus on lower operating temperatures and reduced electricity consumption during extended use.

The 3.5" form factor fits standard desktop drive bays and requires a SATA data connection plus a standard SATA power connector. The drive measures 147mm length x 101.6mm width x 26.1mm height and weighs approximately 610g. Western Digital manufactured this drive in Thailand under model number WD20EURS-63S48Y0, part of the AV-GP (Audio/Video GreenPower) range optimised for write-intensive always-on applications.

Advanced Format drives like the WD20EURS require operating system support for 4KB sectors. Windows 8, Windows 10, Windows 11 and most Linux distributions from 2011 onwards provide native support. Windows XP requires the WD Align utility for optimal performance. The drive is certified to Canada ICES-003 Class B and NMB-003 Classe B standards.

Frequently Asked

What interface does this drive use?

The WD20EURS uses a SATA interface for both data and power. It requires a standard SATA data cable to the motherboard and a SATA power connector from the PSU. The drive is compatible with SATA II and SATA III controllers, running at SATA II speeds.

Is this drive suitable for a NAS or always-on system?

Yes. The AV-GP designation indicates this drive was designed for audio/video applications and continuous operation environments like DVRs and home servers. The GreenPower technology reduces heat and power draw during extended use.

Does it work with Windows 10 and 11?

Yes. Windows 8 and later provide native support for Advanced Format 4KB sector drives. Windows 7 also supports the drive but may benefit from alignment if the partition was created under an older OS. Windows XP requires the WD Align utility.

What RPM does the drive run at?

The WD20EURS operates at 5400 RPM, which is slower than performance desktop drives at 7200 RPM but reduces power consumption, heat and noise. This makes it better suited to bulk storage, media libraries and surveillance recording than as a primary OS drive.
