The FAEX WD Black (2010) is nearly four years old and has been replaced by the WD Black FZEX (2013). Comparing the FAEX and FZEX models shows that the newer FZEX model is around 11% faster on average. The main performance improvements are in the area of sequential writes where the newer FZEX is 30% faster (148 vs 114 MB/s). As a new purchase, the FAEX would have to come at a significant discount to the newer FZEX in order to make it worth considering. The FAEX has a reasonably well-rounded performance profile with above average 4K speeds but it's overpriced and lags the group leaders in terms of value for money. [Nov '12 HDrivePro]
