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]

The new 3TB Seagate Barracuda 2016 (ST3000DM008) replaces its hugely successful predecessor, the 3TB Barracuda 7200.14 2011 (ST3000DM001). Comparing performance between the two models shows that the newer drive has 12% faster sequential speeds, comparable 4K speeds, improved mixed sequential speed and reduced mixed 4K speed. Overall, the effective speed is 12% faster on the 2016 model. Since there is normally little price difference between the two models the 2016 version is the clear winner especially for use as a backup drive with its impressive sequential read and write speeds of nearly 200 MBps. See the current value leaders here. [Feb '17 HDrivePro]
