The (WD20EZRX) is Western Digital's latest green drive. I don't see what's green about it considering that it draws 5.5 watts even when idle, which is about average nowadays. With peak sequential lab read/write speeds of 150 MB/s the performance profile is approximately 20% below average for recent Hard drive. It's not all bad news as the WD Green is priced aggressively so despite its relatively weak performance it still represents reasonable value for money, at least within the 2TB category. Due to economies of scale, larger capacity drives nearly always yield better value for money. Compared to the 3GB 7200.14 Barracuda, performance is very similar but the barracuda offers 50% more capacity for 36% more money. [Dec '13 HDrivePro]

MORE DETAILS

The 1TB Barracuda 7200.14 boasts impressive peak sequential read/write Lab speeds of 195/193 MB/s. These best case burst speeds indicate what the Barracuda is capable of under Lab perfect test conditions. Our real world benchmarks have been sourced from hundreds of users and give a better sense of how well this drive actually performs on a day to day basis. The 1TB 7200.14 has an average UBM sequential read/write speed of 147 MB/s, which is a superb result, especially for a budget drive. With 4K random read/write speeds of 0.77/1.53 MB/s small file performance is also respectable making the 1TB Barracuda a very good all round performer. In terms of value for money the relatively small 1TB drive is not as good value as its larger 3TB sibling but in the 1 TB category this is one of the best value for money drives available. [Jan '14 HDrivePro]
