The Western Digital Green (EARX) was released approximately three years ago and proved to be an extremely popular hard drive. This drive has been benchmarked by our users far more than most, currently 118 samples, so we have a relatively large set of performance data from which we can infer robust performance characteristics. With sequential read/write Lab speeds hitting the 150 MB/s mark, and more importantly, average read/write UserBenchMark (UBM) figures of 125/117 MB/s the 2011 WD Green is no longer able to compete with the newer and in many cases larger platter (1TB) drives of today. Looking at a direct comparison between the EARX and, its direct successor, the EZRX shows that the newer 2012 EZRX outperforms by around 37% in real world tests and 18% in peak Lab tests. This additional performance comes at no extra cost and makes the newer EZRX a far better choice. [Jan '14 HDrivePro]
