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]
