Western Digital Caviar Green (500GB) review

Western Digital’s Caviar Green range of drives eschews maximum performance in favour of green credentials – potentially important in an age where people pay attention to the wattage of their machines and opt for low-power media-centre PCs.

To this end, Caviar Green drives have a range of environmentally-friendly features. The rotational speed of the drive, for instance, varies between 5,400rpm and 7,200rpm – depending on the model – to save power. And here an impressively low power draw of 4W is the result.

Understandably, there’s a performance trade-off. A read speed of 60.5MB/sec is the slowest we’ve seen this month, with a write speed of 52.2MB/sec proving equally disappointing. Access times of 14ms and 5ms for reading and writing files are good, but they can’t compete with the likes of our Labs-winning Samsung drives.

Nevertheless, if you’re looking for a green drive and don’t want to spend a fortune, the 500GB Western Digital is worth considering.
