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]
