It is also a good fit for PVR or DVR setups where thermal optimization and power savings matter. If you need reliable storage for IPTV boxes or continuous recording, this bulk OEM drive delivers the necessary capacity and interface support without unnecessary extras.
Who should skip it

Before You Buy WD20EURX
