This is the current version (2013) of Western Digital's best performing, Black, consumer storage drive. A comparison between the 2013 and 2010 versions shows that core real world performance has improved by around 15%. The 38 month old 2010 FAEX Black is also slightly more expensive at the moment, probably because retailers are slowly running out of stock. With average sequential read/write speeds of 150 MB/s and read/write 4k speeds of 0.8/2.9 MB/s the 2013 2TB WD Black has a solid performance profile but it's slightly overpriced. There is better value available amongst other drives in the group test[Jan '14 HDrivePro]


The FAEX WD Black (2010) is nearly four years old and has been replaced by the WD Black FZEX (2013).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]
