The new 4TB WD Red Pro is an upgraded version of WD's popular Red NAS (Network Attached Storage). The Pro Reds have a rotation speed of 7200 RPM unlike their regular Red counterparts which are marketed as "IntelliPower" but actually spin at fixed speeds of 5400 or 5700 RPM depending on the exact model. Comparing the regular 3TB Red and the 4TB Pro shows that the pro version is significantly faster across the board. The biggest performance gains are seen in the small file 4K area and are a direct consequence of lower access times due to the higher rotation speed of the Pro Red. As well as offering better performance the Pro Reds have 5 year warranties vs 3 years on the regular Reds. Unfortunately it's not all good news as the Pro Red is priced around 50% higher than its regular Red sibling and thus currently represents average value for money at best. [Oct '14 HDrivePro]

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]
